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?
The admins have the ability to and reserve the right to appoint a new head mod. Any unreasonable bans and removals can then be reversed. We actually do it semi often on Lemmy.ml, you can request to become the mod of a community if it has no mods, or all the mods have been inactive for several months.
