The best way to cheat on CS:GO without getting VAC banned EVER is by using linux.
Linux doesn't support Valve's Anti-Cheat *VAC* which means you can cheat as blatant
as you want without getting a VAC ban. The one and only cheat for linux is Aimtux,
it is 100% free and you will never get VAC detected. Although you have to watch
out for Overwatch if you cheat in CS:GO MM. I have made another paste telling you
how you can bypass Overwatch. Just click on my name and look at my pastes.
