Beehaw is a Lemmy instance. However, they defederated from two huge instances, because they’re open registration, and the four BH admins felt overwhelmed with the incoming traffic and unable to manually block trolls, so they decided to just separate from a large chunk of content rather than get it under control.
I’m on one of the two defederated instances, sh.itjust.works, and I can neither see what’s posted there, nor can a BH user see what I post (or what’s up on our server, for that matter.
The other big instance is lemmy.world.
BH has very specific rules for what’s okay over there and what’s not. Check them out and see if you’re willing to live with the defederation for the sake of what their admins define as safety.
