Oof best of luck to you guys on .ml instances, might be worth looking at buying a domain as a backup to migrate to. Don’t wanna be caught off guard like this especially if they are trying to recoup all their urls. I went with a .boo domain to be unique for my instance but there are loads of TLDs out there
One of the problems with the fediverse is that each server keeps its own copy of the content. It is definitely a worry that bad actors push content to federated servers to get them taken down due to the content they now are storing.
