The tl;dr is that lemmy.world and sh.itjust.works have open registration, which Beehaw doesn’t like since it makes it trivial to harass/troll people. Beehaw has some questions you have to answer when signing up to try and reduce the amount of undesirable/negative behaviour, but that doesn’t stop someone from just signing up on another instance and bypassing Beehaw’s requirements.
I think this will eventually be properly solved with some more powerful moderation tools, but Lemmy isn’t quite there yet.
Why are they defederated?
