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
this thing does what you want
But it doesn’t show beehaw for some reason. Since the admins there are basically trying to stop people from joining they may have just asked to be taken off the list.
beehaws own instance link/block list (scroll to the bottom) lists the instances they’re blocking.
