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
If you’re from Lemmy.World and post in a Beehaw.org community then Lemmy.World users will still see your post. But no other instance will. This is because all other instances look to Beehaw to get Beehaw posts. And without Beehaw federation your post never makes it to Beehaw and therefore it never reaches/gets relayed to other instances.
