If an instance is defederated, is there any way Lemmy pings the other instance to let them know, like in the code? I think it might be useful, at least on first thought now, to then maybe hide those communities on the defederated (non "true") instance. Not unsubscribe on the user end, but maybe not populate when searched, hide in subs list, and don't show in feeds. A shadow block or something. Then unhide on refederation since none of the posts that happened in between will be back-synced, so to speak. I think that'll alleviate the confusion. Or it might create more. I don't know. 😂
