its a very very bad player and cheater - but clealy a cheater. (Wallhack)

and anotehr one:

What are we supposed to see there?

are u blind? this guy aims the guys before they come out of cover...

Could've been shot from there before, or spotted on map, or called out by a teammate. My point is that it's literally impossible to say on a 5sec video.

On your second video the enemy is also aiming at the dude you report for wallhack when going out of cover, I suppose he's cheating too then?
