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
That’s the thing. If someone defederates with you, and you wand a community on that instance. Then you are free to make the lost community in your instance. And if re-federation happens, both community can co exist without problems.
Also you can make an account on the instance that defederated. So you still can view the community you want.
