Kind of...
So lets say there is a group called Group A on Instance A. And there is a user called User B on Instance B that is subscribed to Group A.
Then Instance A defederates from instance B. At this point, instance B still has cached copies of the stuff that happened in Group A before defederation. However, they won't see any new content, and crucially, even though they can still see a cached version of Group A, if they try and post to it from Instance B, won't be boosted/relayed/propagated by Group A, so no one else will see their content.
Edit - The exception might be that other users on Instance B that were users of Group A, may see new content generated by Instance B users, though I'm not sure if that's the case
Yeah, that's exactly what I mean. The people on instance B who look at the "C@A" community can still post; their posts won't propagate to other instances but they will see each other's messages, but nobody but the instance B admin will be able to moderate those messages.
IRC and Usenet both have had similar situations.
That's not a bug though, that's just how federation works
It's a corner case that could maybe be handled differently in ways that wouldn't have the surprising consequence, though.
B can defederate from A if it wants to prevent these bastard communities.
