this is why I sugegsted more explicit community ids vs hashtags. you can of course spam anything on nostr (threads, users, dms). hashtags are an easy target. your niche community? I guess, but these are the same problems we've always had and have methods to deal with (WoT, ranking community notes based on number of friends zaps and reactions, etc). this is not a replacement for relay group chats, those are still useful for smaller closed communities with low network effects. I'm more interested in a design for open, twitter-style communities.
