They're confused and likely think that federation means no rules and unconditional access to any server from your account, when it couldn't be further from the truth. I've said it elsewhere but people craving that don't want the fediverse, they want Nostr.

This place is the way it is, why it's enjoyable to be on, because we can and do defederate servers run by bots, trolls, or any other malicious actors, otherwise they run wild.
