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 apologize, you are correct; I assumed every account displayed as “[name]@[instance]” if it wasn’t native to that instance, and that every account that was just “[name]” was a native one, but it seems like some (mainly kbin.social?) accounts don’t do that.
I don’t know why that’s the case. For whatever reason that thread had a lot of kbin people in it, but earlier threads in relation to de-federation had more Beehaw natives and they were generally very supportive of the decision.
