Why on earth people in Nostr enjoy those bloody hell threads?.
I’m tagged in one of those and every time I open Nostr I have tons of notifications of useless replies that basically make quit the app

I do need to put a filter or something in the app where if I’m tagged in any post where more than x people is tagged then I don’t get any notification in my app 

 Damus does that, you can silence the great threads of hell. You also have in the notifications the option to receive only from the accounts you follow. I’m not sure about the other clients.

And sometimes the threads form them so that more users know what accounts to follow since it is one of the ways to have no algorithm to suggest. But it’s annoying 

 I’ll check that option
