I looked up his Stats on the sniper server, hes got about 2 to 1 for kills to headshots per kill, 398 kills 198 headshots to be exact, that doesnt look like an aimbot(at least to me). I usually suspect ppl who have like an 80% or higher headshots per kill stat as being hackers. yet it is the sniper server, and it is with awps so yeah i can see why you'd suspect him. Well, his stats dont check out as a hacker thats my input on it.
Lets see, okay the demo does show him getting some pretty wacky kills, but err i can see within reason alot of them. His misses were pretty consistent too. He aims next to the corners of the crate walls where its most likely for ppl to camp. He did get some weird headshots, but nothing i can conclude as definite hack shots, id guess his quick scoping was just pretty lucky and the reg was really bad, because i did see some of his shots where his aim was directed at the opponents cheast but it instead equaled a headshot. Hacker maybe, its hard to tell imo. Short demo btw.
