UTTP stand for YouTube Troll Police and they basically go to popular YouTubers like MatPat, VivziePop, or whoever and spam "UTTP IS BETTER THAN ____". And when you go to their channel, there's nothing. But there's a link to a Discord and when you click on in, I'm pretty sure you'll see a bunch nasty stuff in there group like child s*x, r*pe, etc.
