Okay, that's fair. The hard requirement for a microblog user to have to follow the community is often too high a barrier (if only because it's not immediately apparent that this needs be done)
That said, Mastodon gets around patchy federation with mention spamming. Threadiverse gets around this with the distributor model (the community itself).
I don't know how to reconcile this from a technical perspective... yet.
Also @db0@lemmy.dbzer0.com this is in response to you as well.
