How the fuck does the fact that weapons are different, change the fact that he flicked exactly onto his head and shot him to death in an instant, again, THIS HAPPENED MORE THAN ONCE.
Because you said you know he's cheating because you're an mlgl33txxcs:gooverwatchxxmlg pro even though cs:go and gmod are insanely different
Because no one ever in the world has ever done a flickshot
A flickshot still needs your model to move, bro. Also, a flickshot doesn't mean shooting the same guy 3 times in 1 second all in the head whilst he is in the air *See Deathrazor's vid.*.
And from what I can understand, this suspicious behavior of his is happening for weeks now, and since he was permabanned some time ago, and being disrespectful in his appeals, him aimbotting wouldn't be a surprise.
