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
Don’t worry about it, sh.itjust.works is a popular instance and Beehaw just want to do their own thing. Unless there’s a specific community hosted on Beehaw that you really want to be a part of you probably won’t notice, as most popular subjects have communities on other servers.
