I don't think it is wallhack.
I have a lot of stuff what is looking like hacks. 3vs3 vs sPec team, I rewatched demo, and tried to watch what i did bad and then i saw my "aimbot" funny situation. I wasn't even looking on screen, just cleaning my laser, and it moved my mouse like aimbot (behind player) for 2,3 sec. Or on airtime some kind of 2s, crouching on checkers(balcony), enemy passed thru and i one balled to balcony, idk how to say it properly... but it was looking right like walhack. And i just forgot to turn off touchpad on my laptop and misscliked on it with my left hand. You can sometimes get "hack" situations, or just good predictions, recon or luck. Not everything are hacks.
