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

I mean, that is literally the purpose of fediverse and federation, right? so people can have their own little bubbles and be as connected as they wish?
How to block entire instances?
Instance admins can do it.
You can’t. Not unless you run your own instance of Lemmy and defederate them.
