Screenshots: None. I was so shocked that I forgot to take a picture, but I remember how he invited me to trade and told me the following things:
GayBenGonnaVacBanYou: GAYBEN IS SO s✿✿✿ COME ON GIV ME SUMFINK s✿✿✿ SO I RENAME IT, SEND IT TO GAYBEN AND LAUGH OF HIM 19:01:37
GayBenGonnaVacBanYou: JOIN ME OR HEME BAN YOU 19:01:44

After this I minimized the TF2 window, closed the game and made a ticket ASAP to Steam Support, because I saw him hacking on a Gold Rush server. This included wallhack, aimbot (partially, only on scouts) and speedhack. I was trying to report him via F7, but it failed due to him having something to cancel ingame reports.

Please understand that I was shocked. I couldn't think fast enough and forgot to take a screenshot.

I need to add a note: He changes his profile name quite often.

Also, new note: He has alot of alts. One of these is called GayBenGonnaVACBanYou. Everytime he gets banned, he makes a new account.
I apologize for multiple posts at the same time.

Without any screenshots there isnt much we can do as we cant act on heresay.
