When I see that sort of stuff I always think of a 17 year old kid in their bedroom being edgy on the internet for kicks, they're clearly trying to illicit a response and if you don't give one, they tend to disappear (although I assume it's still replying as when I try a new client, it's back again). I can see a lot of people thinking that's a hard no from them though.
Now I know what you mean by a hell thread it makes more sense. I envisioned it more like a pile on, which even done in good faith, could be a bit overwhelming.
Maybe a bot that responded to introductions with a simple guide to Nostr? That would be pretty cool IMO, although way over my skill level!
Hashtags are cool.
