I mean I think that is a bad and unhealthy idea. If piefed.social, world or a particular instance wants to set it up that way then go ahead, sure, but I do think it should be up to the admin using the software to decide which servers this should or shouldn't apply to rather than what sounds like an opt-out scheme. I mean sure go ahead, code how you like, who am I to judge, but I'm only saying it in consideration of best practices.

If HB runs into the silly issue again that almost lost them their domain (and temporarily switched to chapo.chat), this code will be a maintenance burden just because of the developer's specific grudge.

I'm saying this as a user happy about the fact that my instance defederated hexbear and lemmygrad, there are cool communities there, but they are an insufferable bunch.
