I’ve been looking for a free Reddit alternative and preferably one that was federated. I’m not really sure how federation works with this though. A lot of similar sites are just personal projects that people made as a hobby that lack a lot of important features or the interface was really ugly.

I haven’t seen how to moderate communities though but the Github page says this can be done, which I consider important since I want moderation to be done by communities and users rather then admins. If there’s a quarantine feature similar to Reddit that would be useful too so I don’t just have to ban communities.

    This would be comparable to lemmy.ml accepting/rejecting accounts based on whether the account email is hosted in “gmail.com”, “hotmail.com” or whichever other third party service.

    That’s true if nothing is expected from the user-instance side. But for example a community-instance may expect from the federated user-instances that they ban user who are repetedly reported for bad behaviour.

    This will be all the more true when Lemmy will federate with other fediverse platforms, such as Mastodon. There, there is a public user to user interaction and so it may be desirable to block the instances that allows undesired behaviours, because most users from there will make no difference and act the same way on Lemmy communities.

    The user-instances in my example also do not serve content from other instances, so they are also very unlikely to see a need to block anyone.

    They serve content from the community instances to their users, whether they host it or not.

    If you really want those instances to disappear altogether and the user accessing communities from client, we lose the feature of user-instances blocking users for all their members, and the members will have to block e.g. all nazis one by one.

    Remember the reason we talked about this: if you don’t duplicate communities then the fact that the amount of popular active topics is limited can lead to huge centralized nodes forming around the active communities.

    They can form, true, but they can also stop growing at some point, as a result of either their own will, the new communities being created elsewhere or cpmmunities migrating elsewhere. In fact, shared communities also don’t prevent these instances to become bigger and bigger.

    Those 2 users can’t be active in an infinite amount of topics.

    Of course I didn’t mean that litterally an infinity of communities will exist some day, just that there are way more topics than what is currently on lemmy.ml so there is a lot of room for other instances to grow.

    Also, the limit of topic that they can discuss simultaneously is not the same as the global one, considering that new communities (dis)appear everyday. And sometimes one will create a new community instead of one that is dying, e.g. setting new rules that they think will improve it. Maybe creating a community on a new instance with different CoC.

      That’s true if nothing is expected from the user-instance side. But for example a community-instance may expect from the federated user-instances that they ban user who are repetedly reported for bad behaviour.

      Nothing should be expected from the user-instance. It should be designed to allow self-hosting your own. If you want to allow people to self-host their user-instance, you can’t trust that they’ll all behave exactly as you want.

      I think an alternative approach if you really want to have bans from an instance carry to the rest would be having repositories of blocklists that are shared between community-instances.

      If you really really don’t want to have blocklists, and you do want to rely on user-instances being trust-worthy… then well… I guess in that case the current federated model that uses whitelists makes sense. But then it’ll be a closed network, not comparable with open networks like XMPP / Matrix, where self-hosting is not only possible, but encouraged.

      They serve content from the community instances to their users, whether they host it or not.

      How do you define “serve”? To me a server is only serving the content that it provides as reponse to the requests done to it.

      If I build a website that uses Google/Facebook as a login method (eg. via OAuth) that doesn’t mean that Google/Facebook is serving all the content in that website. The servers of that website are the ones that both host and serve the content. Google/Facebook is just used by that website as authentication method, but that doesn’t mean that Google/Facebook has any responsibility of the content of that website.

      They can form, true, but they can also stop growing at some point

      True, but I’m not saying that it’ll keep growing infinitelly (it won’t because the amount of active topics are limited).

      My point is that lemmy.ml will continue being central to the network. The other ones can only catter to niche or novel audiences, since they are discouraged from duplicating the communities that have been already created in lemmy.ml.

      It’s fine if you are ok with centralizing communities in specific instances but in that case I don’t see much of a point in federating, just do proper centralization of the communities without the baggage of having to federate across them. Decentralize the services that are meant to be decentralized (identity, search, notifications, etc). This gives more freedom for self-hosting and also makes it possible to reutilize these smaller services to reuse them in other projects outside of Lemmy.

      Of course I didn’t mean that litterally an infinity of communities will exist some day, just that there are way more topics than what is currently on lemmy.ml so there is a lot of room for other instances to grow.

      I agree, but my point was never in conflict with that.

      I already told you before that I don’t think lemmy.ml has all the topics, what I think is that it has most of the active ones and that I expect it’ll continue being the central lemmy node as long as the model continues being designed like this, without a cross-instance way to have topics that doesn’t penalize community duplication.

        Nothing should be expected from the user-instance.

        It’s up to each (user or community) instance to decide with whom they want to federate. It’s true that the user-instances typically wouldn’t have a clear identity in a platform like Lemmy where everything happens in communities, so it seems pointless to block a user-instance for a community-instance; in particular I don’t completely disagree with the statement that the communities cannot expect so much from the user instances in that model.

        But when you think broader than Lemmy, the day it federates with other platforms, like Pixelfed or Mastodon, where interactions happen on the instance, then it has an interest to block instances who allows/encourages behaviours that you wouldn’t want to see reproduced in your communities.

        That’s from the community instance perspective. From the user perspective, it makes sense to join a user-instance that already filters the communities that display unwanted behaviour, i.e. to join an instance who CoC is in agreement with your own preferences, and whose admins you trust to do that job properly.

        It should be designed to allow self-hosting your own.

        This is not incompatible with federation. Users who want an instance doing some filtering job for them can, users who don’t can set up a 1-user instance. Now I’m not familiar with the technicalities of how to currently set up an instance, but if I’m right all one needs to participate in the federation without having an actual server running is an app that talks to the (community-)instance API as if it was a 1-user instance.

        If I build a website that uses Google/Facebook as a login method (eg. via OAuth) that doesn’t mean that Google/Facebook is serving all the content in that website.

        If you completely get rid of the user-instances that’s true. But actually, how different is that from having an account on each of the instances? In fact, how do you do if you want to access your subscribed feed from a web browser? If I understand correctly, assuming there is an appropriate webapp hosted somewhere on the internet, you need to communicate it each of the instances on which you have an account. And so if you are using a shared computer where you don’t want to save your connection data, you need to do it every time.

        The user-instance is a service that hosts your preferences, and provides a front-end that serves content from various community-instances. You can do without it, but then you heavily rely on the client.

        It’s fine if you are ok with centralizing communities in specific instances but in that case I don’t see much of a point in federating, just do proper centralization of the communities without the baggage of having to federate across them.

        For me the point of the federation is not to forbid users to gather in some instances if they want to, but to give access to the service to those who don’t. It ok if most users/communities are on lemmy.ml, as long as they always have the choice to leave it and keep interacting.

        without a cross-instance way to have topics that doesn’t penalize community duplication.

        It is not that clear to me whether storing the community in other servers really help decentralizing. If a community is on lemmy.ml and a smaller one, it is still on lemmy.ml. I’m not sure about how much you empower a small server by using it as a backup of the data that you have on lemmy.ml.

          It’s up to each (user or community) instance to decide with whom they want to federate.

          I know, that’s why I said “should”.

          I’ll repeat what I said: If you really really don’t want to have blocklists, and you do want to rely on user-instances being trust-worthy… then well… I guess in that case the current federated model that uses whitelists makes sense. But then it’ll be a closed network, not comparable with open networks like XMPP / Matrix, where self-hosting is not only possible, but encouraged.

          This is not incompatible with federation.

          Not only did I never say or imply that federation is incompatible with self-hosting, I actually gave notorious federated protocols (XMPP & Matrix) as example of protocols that encourage self-hosting (unlike Lemmy).

          And btw, those other projects actually make it a point to try and minimize the creation of big nodes (Matrix in particular is pushing hard to try and make matrix.org smaller, to the point that they are experimenting with a hybrid P2P model now). Imho, these are examples of federation done right. Lemmy, as it stands with its current design and whitelisting model, is not.

          If you completely get rid of the user-instances that’s true.

          I don’t understand how did you reach the conclusion that I’d want to get rid of user instances. I don’t even understand why getting rid of user-instances would even make what I said true.

          The Google/Facebook example was a way to showcase how user-instances do not serve the content, the same way Google/Facebook do not serve the content of the websites that use them as auth methods.

          The user-instance is a service that hosts your preferences, and provides a front-end that serves content from various community-instances. You can do without it, but then you heavily rely on the client.

          Ah. I see where there’s confusion.

          I don’t think it’s required for the user instance to “provide a front-end that serves content from various community-instances”. That’s the job of the client software, not of the user-instance. The user-instance can be just a simple server that handles user accounts and nothing else. It could be theoretically used for other types of services, it might not even be that much related to Lemmy in particular. It might even be just an “OpenID Connect” instance, maybe with some customizations if required.

          You could have client software that’s completelly web based, using localstorage to keep its local cache (in addition to the remote community-instance having its cache) without having the server who provides the webclient cache or serve any of the community content. An example of this is https://riot.im/app a Matrix client on the web that you can use to access any Matrix instance and consume content via sending requests directly to the instance where the content is hosted. riot.im is not the server, matrix.org (or whichever server you specify when connecting) is. The web client is not responsible of the content you access through it, because it does not serve nor host that content. And the user-instance also does not. Only the community-instance would be responsible of its own content, and because it’s not federated it will not need to take responsability of content hosted by other community-instances.

          Of course the same server that runs a user-instance can have also a web client and can even run its own community-instance, all at the same time. But the point is that each of those is a separate module and they don’t really federate (as in, no two instances of the same type communicate with something that isn’t a service I can replace. And because they don’t federate and don’t cache third party content you remove the biggest reason to do whitelisting/allowlisting.

          For me the point of the federation is not to forbid users to gather in some instances if they want to, but to give access to the service to those who don’t. It ok if most users/communities are on lemmy.ml, as long as they always have the choice to leave it and keep interacting.

          You are not leaving lemmy.ml if you are still consuming its content. You depend on it still. Interacting with lemmy.ml through a third party is just a way to use lemmy.ml. The difference between interacting with lemmy.ml directly is just a technical detail.

          It does not give you much of real end-user advantage. The only difference is that the user details will be hosted in a difference instance, but you don’t need federation for that, as we have already discussed.

            I don’t understand how Lemmy protocol encourages to not self host. I’m not much familiar with Matrix, but to me it seems that the only difference is that a Lemmy community is only hosted on one instance while a Matrix room is duplicated on each of the users’s home server.That’s probably very naive, but wouldn’t it mean that in practice one would need more memory to self host a Matrix 1 user-instance?

            If it’s about the fact that it uses whitelisting instead of blacklisting, I already told you that I’m also in favor of the latter. But this should only have impact on the time it takes to federate, not on the state of an instance once it’s set up. After all, the only difference is that the other instance’s owner needs to press “ok” before federating.

            I don’t understand how did you reach the conclusion that I’d want to get rid of user instances. I don’t even understand why getting rid of user-instances would even make what I said true.

            I think we misunderstood each other about what “managing a user account” means. I define the user-instance as a server where the user has an account, and who federates with the appropriate community-instances so as to serve their content to the user.

            Note that I mistakenly used the word “frontend” here, but I never thought that this instance was the same as the client. Sorry about that ! In your Matrix example, matrix.org is definitely what I would refer to as the user-instance.

            I noticed later that by “managing a user account” you probably only meant “provide an ID who allows to avoid setting up a new password”. Is that right? That thing is not an “instance” of the networking software, as it doesn’t know anything about the software in question, and only provide some kind of token that allows to create an account on the community instance in question. (the account may be as simple as a pseudonym and a reference to the ID, but may also possibly contain additional info or keep track of the user’s activity on the instance)

            This brings me back to my previous comment. Say the user-instance (as defined above) is replaced with a simple ID-provider, and serving the content from the community instances becomes the client’s job. This means that you don’t have a cross-instance profile anywhere on the internet, and need to manually connect to any instance where you have an account each time you connect on a new machine. Right?

            Now it seems to me that you not wanting user-instances (I still think you don’t want them if they are defined as above, but please correct me if that’s wrong !) is one of the reasons why you would invoke meta-communities as a way to keep track of a cross-instance list of communities.

            And because they don’t federate and don’t cache third party content you remove the biggest reason to do whitelisting/allowlisting.

            Again, I don’t agree that’s the main reason, but we discussed that already.

            You are not leaving lemmy.ml if you are still consuming its content.

            Sure, but remember that white/blacklistings on the Fediverse are not transitive. So I can federate with both lemmy.ml and with other people who are on instances that don’t federate with lemmy.ml. Unless some instances federate only with lemmy.ml, one is never incentivized to stay on lemmy.ml if they want to leave it.

            Note that this also works in the context of your original proposal of cross-instance categories : if you follow a category that is open to lemmy.ml, most content that you consume there will come from lemmy.ml. In fact, except if your instance blacklists lemmy.ml. But I’m not sure about why stopping to interact with the biggest instance would become a goal per se.

              If it’s about the fact that it uses whitelisting instead of blacklisting, I already told you that I’m also in favor of the latter.

              I don’t like whitelisting either, but if I opened my own instance with the current state of things, I would actually apply whitelisting on my server myself to limit what I federate with.

              The problem is that the way the federation works in Lemmy would force my instance to cache and publicly serve content from any server it federates with. And I don’t want to host illegal content and get in trouble.

              So the issue is that whitelisting is the only way to safely host a lemmy instance without requiring close eye maintenance. This is what I see as the biggest problem.

              the only difference is that the other instance’s owner needs to press “ok” before federating.

              If it’s that simple, the whitelisting would not be very useful to protect against bad instances. It’ll either be inefficient (if not enough control is applied) or be a burden (if too much control is applied). The line that divides those two is diffuse and it’s likely we’ll get both false negatives and false positives, so there’ll be mistakes either way, ending up both being a burden and inefficient.

              It also complicates things to add a human factor to the process of setting up your instance. You’ll have to do some public relations with the other instances and the other instances might want to keep an eye on your instance which adds to the maintenance burden, specially if lemmy ever becomes popular and it ever reaches numbers in the hundreds of instances.

              With an email server or an XMPP server, self-hosting is enough to communicate with everyone. But with lemmy I’ll have to do work for every instance, at that point why not just create an account in that instance, which might actually be instantaneous. I’d rather make a multi-account client that abstracts my identities as if they were one instead of hosting my own server to have control of my identity.

              I define the user-instance as a server where the user has an account, and who federates with the appropriate community-instances so as to serve their content to the user.

              It would defeat the whole point if I meant for the user management instance to federate with instances of its own class. This whole branch on the conversation thread was about me wanting to explore the idea of federation not being needed to do what Lemmy is doing right now, that instead of federating you can separate the services in a more “microservice”-ish like model (but not as extreme), making it not only simpler but also more modular and reusable.

              I noticed later that by “managing a user account” you probably only meant “provide an ID who allows to avoid setting up a new password”. Is that right?

              Yes, more or less. It’d act as an authentication server (I explicitly linked OpenID’s wikipedia page right after mentioning “user account management”) and it’d also allow users and its sessions to be created/removed/edited (again, that’s what “managing” means when we talk data). Any operation that related to the user and not the content. It does not view/add/remove/edit (manage) any kind of community content, that would be content management, not user management.

              This means that you don’t have a cross-instance profile anywhere on the internet, and need to manually connect to any instance where you have an account each time you connect on a new machine. Right?

              Not necessarily, there could be user metadata stored in the user service. Things like name, profile, personal website… but also what instances the user has a token with. I expect the token exchanged is long lasting so the user-instance needs to keep track on its side about this already anyway. Much in the same way as how Paypal keeps “authorizations” for websites the user has allowed payment to be automatic, the user-instance would allow the client to know of those websites and be able to access them with the token without manually having to connect (done from whatever the client is, without serving the content). Also the notifications system could be part of that instance, or it could be its own separate service entirely.

              That’s the kind of instance I’d be happy to self-host, because it’ll be mainly personal data related to my user. I’m not so interested in hosting communities.

              Now it seems to me that you not wanting user-instances […] is one of the reasons why you would invoke meta-communities as a way to keep track of a cross-instance list of communities.

              It’s the other way around. Don’t you remember what started this “federation” topic?

              To me cross-instance “topics” (either tags or meta-communities) would be the one thing that would make federation useful. Without that, I don’t see the benefit of federation. Which is why I was talking about separating the user management (and notifications) from the content management, so that you can achieve shared accounts without having to federate.

              Sorry if I’m repeating myself (I think I’ve said that same paragraph in almost every comment, with different words) but I don’t know how else to explain it.

              Unless some instances federate only with lemmy.ml, one is never incentivized to stay on lemmy.ml if they want to leave it.

              Again: “You are not leaving lemmy.ml if you are still consuming its content.”

              If you are using the non-transitive property to consume lemmy.ml content, then you are not leaving lemmy.ml, even if you are connecting to it through a different instance. Even if you don’t have an account in lemmy.ml, you did not really left it. Since we don’t have a cross-instance “topic” to subscribe to, and since you don’t want “duplicated” communities, you have to keep relying on lemmy.ml as the central node where most of the active communities are.

              I’m not sure about why stopping to interact with the biggest instance would become a goal per se.

              It doesn’t have to be a goal.

              But in that case just embrace the centralization of those communities, what’s the advantage of federating? The things you want to share cross instance, share them by having a separate service handle them. Only if there’s a reason to have community-servers directly communicate with each other (eg. cross-instance “topics”) does federating across them become useful, imho.

                The problem is that the way the federation works in Lemmy would force my instance to cache and publicly serve content from any server it federates with.

                So you say that as soon as you create an instance, everyone can see its frontpage, and that there is no way to create an instance where the only thing that outsiders can access is your profile? That would solve your public serving problem, right?

                If it’s that simple, the whitelisting would not be very useful to protect against bad instances.

                What other difference are there?

                It also complicates things to add a human factor to the process of setting up your instance.

                Ok I was probably wrong in saying “setting up” there, as if you had to decide on day one what you federate with. How it would actually work is that you can vet any new instance that you encounter (e.g. via a crosspost, or via a new community there that is announced on some instance you already federate with) before sending it a federation request, that it then would have to accept.

                In fact, do you know what happens when a user from an instance that I don’t federate with comments a post that I see? Is it simply hidden? Does it say “comment from remote instance hidden”? Or does my instance’s admin receive a suggestion to federate with them? Or maybe in Lemmy federation is only about which communities I can access, but doesn’t hide comments from unfederated (with me) instances?

                It does not view/add/remove/edit (manage) any kind of community content, that would be content management, not user management.

                Filtering the content a user has access to and constructing their frontpage can be seen as part of managing their account. As I said, we misunderstood each other’s definition of managing the user account, that’s ok.

                To me cross-instance “topics” (either tags or meta-communities) would be the one thing that would make federation useful.

                We said already several times, federation also offers the advantage of being able to delegate filtering tasks to the instance you register on. Each user doesn’t have to allow/block each (community-)instance by themselves, but can leave that to an instance admin that they trust.

                It also allows the instance to store its users’ history (or outbox in activitypub language).

                If the content is served to you by your user instance, it also means to don’t have to communicate with the community-instance every time you want to read content from it. This means that the community-instance cannot track your (passive) activity, which I think is also valuable.

                What about crossposting?

                Again, the federated network can have one-user nodes, but federation offers the possibility to delegate tasks that you don’t want to do yourself.

                Again: “You are not leaving lemmy.ml if you are still consuming its content.”

                Again, you can completely leave it in the sense you mentioned by registering on an instance that doesn’t (plan to) federate with it. So you can leave it, and keep interacting with the rest of the network, the part that interacts both with you and with lemmy.ml.

                (This is of course not the only acceptable definition of “leaving” in that context. Isn’t one user closing their gmail account to register with another provider leaving it? Would you say “you don’t leave gmail if you can still consume content from it”?)

                  Yes, essentially. It’s too much of a problem having to publicly host content from other people’s instances that you might have not much control on, unless you activelly monitor them constantly, which is why I think it makes sense lemmy instances use whitelisting. Even if whitelisting is an obstacle in federation.

                  However, you cannot do what you proposed to solve the same problem when it happens in community instances. As long as community instances federate, whitelisting is the safest option. This is why I propose they should rather not federate among themselves.

                  What other difference are there?

                  Between whitelisting vs blocklisting? I’m not sure if there are any other significant differences than what we already discussed.

                  In fact, do you know what happens when a user from an instance that I don’t federate with comments a post that I see? Is it simply hidden?

                  As far as I understand, instances are unaware of what instances not in the whitelist might have commented, because they do not host that content. In the words of a lemmy dev: " your instance may not show posts or comments in a remote community if the author’s instance is blocked. Votes are also not counted from blocked instances " …I expect this means the comment will simply not appear at all, but I haven’t tested.

                  We said already several times, federation also offers the advantage of being able to delegate filtering tasks to the instance you register on. Each user doesn’t have to allow/block each (community-)instance by themselves, but can leave that to an instance admin that they trust.

                  And I already answered that this can be done with shared blocklists. Anything you want to share, see if it can be made made independent, instead of assuming cross-instance federation is the only way.

                  It also allows the instance to store its users’ history (or outbox in activitypub language).

                  Can’t the feed just reference to community content hosted in community servers without having to host the content itself? The client may load that content in the feed requesting it from the community servers directly, without it having to be cached in the user-instance.

                  Or, alternatively, request separately the history feed for each community instance the user has interacted with within the given timeframe (the user instance should know which ones) and merge their history client side.

                  If the content is served to you by your user instance, it also means to don’t have to communicate with the community-instance every time you want to read content from it. This means that the community-instance cannot track your (passive) activity, which I think is also valuable.

                  You can already do that client-side. The client can cache all the requests on local storage so it doesn’t request the same data every time it wants to read it. This actually was suggested by one of the lemmy devs before.

                  Again, you can completely leave it in the sense you mentioned by registering on an instance that doesn’t (plan to) federate with it.

                  The network will be significantly crippled though, since most active communities are on lemmy.ml.

                  Would you say “you don’t leave gmail if you can still consume content from it”?

                  If gmail has a significant majority of the network of email and you still have the need to communicate primarily with gmail accounts, then yeah, you still depend on gmail, even if it’s not who hosts your email account. This gives a lot of power to gmail over the email protocol, even if you don’t have a google account, your emails will get into google’s hands.

                  Imho, one of the points for federation is trying to avoid depending on big central nodes. If one node is down, disappears or becomes “evil”, the impact is not as big as long as the federated network is well balanced.

                    As long as community instances federate, whitelisting is the safest option. This is why I propose they should rather not federate among themselves.

                    Of course, I agree that if we separate community instances from user instances, there is no need for community instances to federate with each other. They only need to federate with user instances.

                    In turn, user instances may or may not federate with each other. That’s the rest of the discussion. If they don’t, it means there is no user-to-user interaction independently from communities, right? For example no direct message feature.

                    Anything you want to share, see if it can be made made independent, instead of assuming cross-instance federation is the only way.

                    So you claim there should be a separate service for each community-independent feature : one for providing ID, maybe one for DM, one for sharing blocklists, … That is indeed another way to do it, I don’t think I ever claimed federated user instances was the only one. It is still one way, and it has its own disadvantages but also advantages over the one you advocate for.

                    The client can cache all the requests on local storage so it doesn’t request the same data every time it wants to read it.

                    Maybe true if you want to check a specific content, what I mostly meant was that if you want to check an updated community feed, the community instance is aware you do that request. The user instance is an intermediate who doesn’t have to tell which user is checking the feed.

                    But even for the former use, it is not always true : what if you are using a webclient from a shared computer?

                    Can’t the feed just reference to community content hosted in community servers without having to host the content itself?

                    First, same argument as before : you need to tell every community instance in you subscription that you are checking your history.

                    Also, that means basically that you lose your own content when that instance shuts down.

                    For this latest two points, the idea is really that you can trust a single (ideally small scale) user-instance instead of vetting each community instance that hosts content that you are interested in. Can be useful if most communities are on an instance that one day turns evil :)

                    even if you don’t have a google account, your emails will get into google’s hands.

                    Not negating that.

                    Not having an account is still an advantage though, as google doesn’t know anything about what you exchange with people who don’t use it. Federation allows you to

                    • get that level of “leaving the main instance”

                    • keep in touch with people still on the main instance

                    • keep in touch with people who completely left it, without exposing them to it.
