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?
I think the only solution really is probably to self host. Or, for multiple instances to have duplicate instances and to cross post on all the communities. You already see this happening, especially with COVID communities across Lemmy and Lotide, but also with news and tech communities I think
