Recently this guy who i've been playing with for a while (We started playing it together after not touching since 2019 we have maybe 600hrs between the 2 of us so we are silvers fr) but he just exploded in skill growth out of nowhere after playing like a sleeping grandpa for the longest time.
His preaim crosshair placement was getting better, his aim was getting better, but i noticed his utility usage and movement/positioning was not improving. I was just convinced he was playing a lot of practice maps and watching videos to get better with aim.
Our other friend who's been playing CS since the actual start of CSGO hosted a private match and told us we should 1v1 so he could watch us and identify our weaknesses a little better.
He spectated my friend and told me in a private message that he was tracking me through a wall and was pre aiming the angles I was going to peek him.
He made a joke to my friend about cheating and he got defensive and suddenly he started playing like he used to.
It got me thinking if he actually is cheating.
I watched the playbacks for some of the games I played with him and to say the least he was doing some weird stuff.
He was pre aiming for off angles and not clearing angles you should clear but only when nobody was there, He was holding really small angles that he really had no real reason to hold but only when someone was slow walking that direction to peek that angle.
He only plays weird when he's alive but once people die and spectate him it always looks like he wants to peek the enemies holding off angles but doesn't want to look suspicious
I also noticed on a Mirage game that 2 T's were slow walking thru Under while it was smoked off and my friend was in Con and his crosshair was over them as soon as he got into Con.
I actually don't know what to do, I want to upload the video evidence I compiled but I don't want to dox him, myself or our other friends that we play with.
