Idea: if you mod a community on a lemmy.somewhere you should be able to migrate it to lemmy.elsewhere which would include all post & comment links being forwarded and subbed users having their subscription updated to reflect the new location.
I’m aware this would be a way down the road as user account migration alone is still not great but it would be a great feature for the fediverse to have to avoid centralisation and mod/server admin wars.
You must log in or register to comment.
Yes. It is a must have feature, actually.
I think it should be a “copy community” feature, then mods can just prevent posts in the old community and make a sticky that points to the new location.
Making users automatically subscribe to a community on a different instance (even if it’s “the same community”) is pushing it a bit in terms of moderator power. Also makes things worse in terms of exploits and others have pointed out.
Mastodon uses aliasing for account migration. Your old account still exists on the original server, but it points to your new account. Following the old account automatically reroutes the follow to the new one. This could be done at the group level for lemmy without needing to manually lock the original group or ask users to find the new one.
The issue is that users might object to subscribing to a community on a particular instance. I guess it’s not the end of the world, you can always unsubscribe but I can imagine some people being very upset to be associated with certain politically leaning instances or worse.
Perhaps a notification when it occurs, so you could unsubscribe if you wish.
That is what happens on Mastodon now when someone moves their account from one server to another — you get a notification of them following you from the other server.
I don’t use mastodon. Do users need to reciprocate? So if I followed you and you moved server would I still get a notification, or only if you follow me?
Can anyone follow you, so does the notification let you know that it’s a change, rather than a new follower.
It is all automatic.
You maintain the same relationship after the move.
If you just followed them, but they didn’t follow you — that continues after the move.
If they just followed you, but you didn’t follow them — that continues after the move.
If you followed each other — that continues after the move.
It is all automatic.
…
As a user, if someone who follows you moves their account, you see that as a new follow in your notifications.
Have something like a mass message to subscribers with a link to the new instance.
Then the old instance owner can take the old community name back.
Data portability for instances and users is imo an essential feature of any fediverse app, and sorely missing here on Lemmy/Kbin. We’ve already seen the issue surface with the hacks in instances last week and other instances going down suddenly. Like mastodon, we need to be able to take our data to whatever instance we want easily.
Risky. Some hacker exploits a vulnerability, takes over the community and migrates it to some other server… then what?
Also, if a community leaves a specific server, what stops anyone else from re-creating it in the original server?
To the first, rollback.
To the second, is that a problem?
To the first, rollback.
for the first, you still have everyone subbed to the newly created community made by the attacker and all the links are still updated
if instead of migrating everything right away, you have the original server of the community give redirects for each request, then that won’t help if the original server is closing down, but it’s probably the only right way to do it, I guess you could also have an angry instance admin disable the redirect to keep the community on their own server
To the second, is that a problem?
migrating and then recreating the original is actually an issue that Github has when you rename a repo, Github will give redirects for the links to the old name of the repo, but if you create another repo with the old name then the redirects are no longer served and if someone clicks on an old link then they end up at the repo that stole the name instead of the repo that was renamed
so if let’s say there was an official linus_tech_tips community on beehaw and they moved to lemmy.world, some random person could create the community again on beehaw after the migration to appear official and hijack all the old links out on the internet
you fix that by keeping the old name reserved after migration, I don’t really think that’s a big problem in this case
I actually liked @Neato@kbin.social’s idea, instead of “migrating”, you just copy the community and then send a message to every subscriber, close the original community, and put a pinned post at the top, maybe a message in the sidebar too
But that also makes it incredibly easy for communities on defederated servers to set up shop elsewhere.
And those communities may be the sole reason that the server was defederated in the first place.
I think a possible outcome is that the larger instances would have to put a stop to open creation of new communities, to prevent toxic groups from setting up shop and moving all their objectionable content and users into the space.
I think it can be solved with a two step process. First, the mods of the community and only them can make a request to move from instance A to instance B, and second, the admins or mods of instance B approve the request, importing only the posts and comments from federated users.
Let instance admins approve or deny the requests then
A good community leaving a bad server can maybe work if the server doesn’t just turn that off.
A bad community that was hosted on a bad server can continue to be blocked on a server level.
A good server tolerating a somewhat bad community will let users continue to block communities.
Two good communities on one server might grow large and want to split servers.
What if an instance were able to block specific communities on other instances without defederating?
Users can already do so, what would instance-level block bring?
Allow the admins of the instance to enforce their rules?
Say you have an instance with a “no-NSFW” rule, for people who don’t want to randomly come across NSFW communities. Their admins could take care of the curating of rule-breaking NSFW communities without having to resort to defederating from the entire instance. This doesn’t have to be an outright block but just a filter that could prevent the community to show up in “All”.
That will break federation in a very bad way. Imagine you’re on such instance which doesn’t want NSFW content, but you subscribe to a NSFW community. Admins block it and you don’t even know it, you just don’t see your community anymore. What do you do? Create another account elsewhere? The whole point of federation is to use one single account EVERYWHERE. Otherwise it’s no different then Reddit and Hacker News - just two random online sites and you have to create a bazillion of accounts everywhere.
Admins should not block anything coming from outside instances. Admins should never defed. Instead you, as a user, should have all the tools to moderate your own feed. If you give away your rights and freedoms, you’ll lose them forever and you’ll be abused on Lemmy the way you were on Reddit.
If you want your freedom – whatever that means to you – you go to an instance that represents those values. Admins that run their own instance get to decide how they moderate that instance. And that includes blocking (or defederating) whole instances, communities, or individual users. You don’t have to sign up to one that does something you don’t like.
Besides, you don’t seem to understand the importance of moderation. If it wasn’t for the ability to defederate, we’d have tons of fake instances with fake users creating fake posts. Not to mention people going out of their way to make others feel miserable. Do they have the right to spew their hatred? I have my opinion, but it doesn’t matter. I happen to also have the right to join an instance that has a policy to take care of that stuff so I can browse for things that actually interest me.
Do you people even understand what is the point of federation and Fediverse? Because it seems you don’t and I’m tired explaining… In short, you should use Reddit instead.
then the question is why the hell did you make an account on an instance that doesn’t want to interact with NSFW content (presumably it’s in their rules) when you want to interact with NSFW content; like I don’t see why you’d do that if you knew the rules beforehand
Do you understand what the point of federation is? The point is to have one single account to interact with the whole Fediverse. It shouldn’t matter where you register your account, all Fediverse should be accessible to you.
that’s not the point; the point is to not have a single group dominate the site and to make it easier to avoid bad actors (bigots + fascists, because there’s a lot of that online) by just blocking the instance they live on
the “one single account” thing is a bonus, but definitely not the main reason for federation
This seems silly. Just have new users default to having the “don’t show NSFW” setting enabled.
At first I thought this was a great idea. But need to understand a bit more about the security implications for those that subscribe and post to the communities that want to do a move. It’s one thing to trust your credentials to the host server, but quite another to implicitly trust the community mod who wishes to move. How would the old posts migrate? How would integrity of the constituent posts be preserved? How easy would it be to inject comments into to historical posts and republish them on the new, official, server? Could you be held liable (whether officially or through reputational risk) for posting content that wasn’t really yours? Maybe there are good mechanisms to maintain integrity of data? I’m just not sure what they are.
I think there may be implications to this that are not obvious.
Happy to have these concerns assuaged, of course!
Possibly some kind of democratic voting system would work? Or maybe the mods must all vote to do the move. Just an idea from when I saw another instance do a vote (for federation) using emojis, on a post, and they just counted them basically.
(edit: The mastadon method seems feasible though posts need to move too.)
It’s going to be incredibly necessary in the long run. Decentralized means some proportion of important communities are going to be on servers that will eventually be shut down for various reasons. Not everybody who’s running an instance now will run it forever, but there may be communities with important conversations that folks will want to preserve.
Mastodon has account migration and Lemmy community migration should work similarly.
Mastodon migration is still somewhat limited.
Your posts don’t transfer over, being the big catch.
(Most everything else does, though)
Ok, Calckey migration, then.
And Lemmy should also have account migration.
I made a tool that does this until we can get something baked into Lemmy itself: https://github.com/CMahaff/lasim
There are a handful of other options out there too if ya search for em. Mine backs up / copies subscriptions, blocks, and a handful of profile settings.
It should, but the Lemmy devs are swamped right now to add more features. Before, they had a pretty small dev team too. Now that there’s a lot more eyes on Lemmy, hopefully we’ll get more features while they iron out the stability issues.
Additionally, if your server disappears *cough* VLemmy *cough* you should be able to load a backup from somewhere and register your channels on another server. I realize this is still a crawl-walk-run scenario and that’s going to be far in the future. But we can still hope for it.

server gets defederated, server moves to new server, defederation bypassed.
Just thought I’d flag this up: !issue_tracker@lemm.ee
It’s a community to coordinate idea suggestions as well as image tracking. Perhaps this could be flagged up over there with a link back here or cross-posted.
Does a bot post issues raised / commented on Lemmy, back into GitHub? Or is it just one directional?
I think they are still figuring that out.
Cheers!
This is indeed a very important feature. It needs to take into account that if similar name community exists on another server how the merger would proceed as well in terms of exporting and importing cache of posts and comments.
But generally it should be easier to transfer from one instance to other.
And somehow be redundant/mirrored/backed up. Hacks, crashes, instance owner gets pissed, decides to take their sandbox and everything in it. Lots of ways and reasons that communities wlll disappear and a way to recover might be helpful.
All of this could be there with the matrix.org protocol. The matrix protocol saves the comments and content in a directed graph, and that graph is copied to every instance, once one views it. It may not scale though. But it has benefits, such as encryption (making communities private or gated when under attack)
I’ve been out of this loop for decades, but can see a train wreck if this vulnerability isn’t addressed.
Matrix says, “The functionality that Matrix provides includes: Creation and management of fully distributed chat rooms with no single points of control or failure…”
I don’t know what ‘fully distributed’ means. But one potential way of securing everything might be through something like torrenting. Have all Instances on several servers, such that the loss of a single server or Instance couldn’t wipe out a community. If that happens more than a few times, I could see federating setback considerably.
That’s my two cents, and I’ll leave it to the smarter and more capable folks to resolve.
when a user on a server is in a room it is “hosting” the room so if the server the room was made on goes down, everyone who’s not on that server can still talk in the room, that does make the hardware requirements higher compared to XMPP for sure which is a downside but I do feel like the positives outweigh the negatives personally at least
Proper backup protocol raises HW requirements. But if you want to do something right, it’s just the cost of doing business. There’s the old saw, “If you don’t have time to do it right, when will you have time to do it again?” But there may not be an opportunity to do this one over.
I foresee moneyed interests working steadily, diligently, relentlessly (with paid labor!) to help this entire effort fail. The success of this concept represents the loss of inestimable billions to today’s dominant platforms. Those corporations will, as always, work hard toward their self interests.
Yep, I lost my communities when vlemmy shut down
Agreed!
