I only just learned today that, when someone from one instance gets banned from another instance, that person not only is no longer able to interact with the second instance, but people from the second instance actually can’t see anything the person said from the moment they got banned even though they’re still there. I’m disappointed to learn all my friends who got banned from my instance are still saying stuff and nobody told me, making it more akin to an instance forcing everyone to block them (because individuals blocking each other the same way work like this). And this is coming from the person who has fantasized about universalization of federation.
What’s something about the fediverse that was most recently unobscured but that you know now?
If a comment were removed from instance A, you could go look at the same post on instance B and see whether the comment is also removed there. You don’t need a user account on either instance to do this.
