If A, B, and C are federated and A defederates B and B does not defederate A, then it would look like this. A>B=C

A cannot see B, B can see A through C, and C can interact with both. Comment federation when B comments on A can be a bit spotty, from what I’ve seen.

    As far as I understand, this isn't quite right (unless it's changed recently).

    If A defeds B, then A no longer sends new posts to B, accepts comments or posts from B users, or receives new posts from B. Any comments from B users on A's old posts (made before defederation) are no longer acknowledged by A.

    I think A users can still interact with B's posts, but then I haven't seen any beehaw users in forever. So perhaps not?

    C can obviously still interact with both A and B posts normally. On posts from C, both A and B users can still interact.

    So, in short defederation creates a hard wall preventing interaction between A and B. The only way A and B users can interact is on C.

    It's unfortunate as beehaw would have benefitted from a uni-directional defederation (i.e. preventing .world users from posting on beehaw, but not preventing .beehaw users from posting on .world. Unfortunately, it's both.)

    It may have changed in the last few months, but I specifically recall seeing hexbear user comments on lemmy.ml posts well over a month after the one-sided defederation while on my sh.itjust.works account. I checked from at least 3 separate instances, lemm.ee, .world, and .works, as it was more than a little confusing for me. That’s also how I learned about spotty comment federation.
