nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s implemented pretty aggressive rate limiting on the Damus relay which seems to stop that. nostr.wine is a paid relay, so spammers don’t use it. Not sure what nostr.band is doing to block the spam.

So, when you try to search stuff on nostr or check some hashtag, you don't get any RGy stuff?
I haven't seen any RG stuff since I reduced my relay list down to this. It's only been one day though. I think most Nostr clients will only display notes from relays you read from when you search for things.
