Ok guys I'm not here to throw accusations but something is not quite right and therefore I would like you to have look with your expert's eyes. If I'm mistaken please accept my apology right now. Sorry for quality of this video
When you record someone, you should hold the TAB button then wait for them to respawn (skull disappears) then you click their name. If you cycle through the players, you miss out on his kills. When you start watching the player, you do not open the scoreboard.
You need to put timestamps of where you think he is suspicious.
He doesn't look like he is using aimbot because his recoil pattern is consistent with the MDC.
few times I noticed his aim snapping about, pretty much like in cachopelo's last video Godfather1930 ( check his zoomed and slow-motion videos)
Look at 8:47-8:48 for example. Sudden small jump in aim while shooting at enemy.
