Title says it all. I’m especially interested how likes / upvotes will work with federated instances
All actions, including votes, get sent to that federated community, which then announces the action to the other instances. This is currently working at our test instances at enterprise.lemmy.ml .
Is it like the rest of Mastodon where if a server goes down, the communities on that server go down too? Or is it possible that if several servers have users that are part of a community, that the community can still operate if one of them is down (even the first server that started the community)
Users from anywhere can subscribe to a community, but if that community goes down, new content can’t get added.
Thanks. I assume spam will be handled by moderators of the community banning users and instances?
Yep, mainly through instance blocklists / allowlists. Mod actions still do need some testing, but they currently work.
Does this mean posts and communities are also reproduced across instances?
They are pushed go connected instances, yes.
