This guy is a legitimate psychopath, in every aspect of the term.
Just because he was getting dominated in a CSGO competitive match, he decided to stalk me while in mid-game, change his profile picture to an image of me, changed his profile name at least 17 times to my name alongside insults, and posted my personal info in-game for 30 minutes straight.
This guy is seriously mentally unstable. This is the type of person that would stalk and end up finding you irl only to try and kill you just for beating him in a video game.
You need to be detained. You're a danger to people around you. You're not normal by any means, and you need medical help immediately.
