Basically you create a note, tag as many people as you can and send it. Every time someone comments on that note EVERYONE gets notified. I think "hell thread 6" was the worst. It blew up peoples notifications for days 🤣 (put it showed us flaws in the nostr protocol. So basically a fun way trying to break stuff)

Thing is, nobody has the balls any more to create a hell thread cause now everyone knows how mute lists work 🤣
