I had recently called admin on this player https://steamcommunity.com/id/youngmobbin/ , just yesterday he was harassing someone through chat and via voice, An admin joined in and both gagged/muted him. Mind you often times when he is on he provokes people and enjoys it. A friend of mine comes back after a few weeks of being offline from TF2 and their experience is ruined and drove them away too. After my friend leaves he celebrates by saying "I'm a professional at making people hate themselves"
For reference here are some chat logs by him (they changed their name to She/her)
