Why YSK: Beehaw defederated from Lemmy.World and Sh.itjust.works effectively shadowbanning anyone from those instances. You will not be able to interact with their users or posts.
Edit: A lot of people are asking why Beehaw did this. I want to keep this post informational and not color it with my personal opinion. I am adding a link to the Beehaw announcement if you are interested in reading it, you can form your own views. https://beehaw.org/post/567170
Lemmy got a large influx of new people (you probably noticed that), and those new people weren’t reading their gidelines (that are more strict than usual) before posting there.
If you decide to make an account there, make sure to read their guidelines first.
