He told you off when you were named "Harry big fat gay" and you clearly didn't stop after that
You kept on minging around on the server purposely delaying the match making people leave and in general just kept on trying to be a annoying as possible. The last thing you did wasn't big in itself but it's the straw that broke the donkey's back. The fact that you had been a minge the entirety of your stay made Harry believe you weren't saying that as a friendly gesture.
Why does ex staff members only get on TTT to act like a minge lmao.
