Does Lemmy have a way to counteract a mod taking down a whole community? (lemmy.ml)

After seeing what happend on r/antiwork over at Reddit. Does Lemmy have a way to prevent somthing similar, like could another instance decide to preserve a deleted community and not have a single point of failure?

The same question can be asked if an instance suddenly closes down, can other instances keep the communities alive?

If an instance goes down, then pretty all much all data on that server will not be accessible. So the communities, posts and users on that instance will be gone.

Maybe lemmy can implement something similar to the matrix protocol.

Matrix is really a decentralised conversation store rather than a messaging protocol. When you send a message in Matrix, it is replicated over all the servers whose users are participating in a given conversation - similarly to how commits are replicated between Git repositories. There is no single point of control or failure in a Matrix conversation which spans multiple servers:

So a community will remain accessible even if the homeserver goes down

If an instance goes down, then pretty all much all data on that server will not be accessible.

Also wanna add, that if any servers have been federating with communities that live on a dead server, they will still have a backup of all those pushed posts and comments ( which starts happening immediately after one person subscribes to that remote community).

That would dramatically increase server resources necessary though

yep that is a problem.
