Agreed.
I haven't watched the demo's but I also believe this guy is a hacker. I tried to demo him earlier but every time i went in spectate he would totally change his gameplay. Like he would be on a kiling spree for few rounds and as soon as i switch he would suck balls. What started giving me suspicions was when I was a Vaga myself on Italy, I would teleport into most random places at most random hights nd he would just pick me off instantly. My guess is that he has walls with skins where it makes vaga visible and a possible aimbot. Also another thing that cought my eye was that he would fallow people with his aim cross thru walls as he could see them nd know exacly when they cross the corner.
