Really short demo, but he left soon after I switched to spectate. May or may not be enough for you to make the call.

I can say when I was on earlier, I noticed there were many headshots he was making so I went to spectate but he had left also, obviously he came back on later. My 2 cents worth.
Aimbot captured on demo. Headsnap is banned. Thank you for the report.
