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?
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).
