Me thinks she doth cheat too much and is just using this as a cover up.

VAC doesn't detect your level changes at all. Thats how the 10th prestigers get off.

Even if VAC did, it would have to have a program that is injecting the game running in the background (or some other hack) 3 times before it would put you on the "Ban in next batch" list.

Go ahead and hack, your accounts are all pasted on the highscore and IW can easily detect whether you
hacked or not. Hackers are just *******.

On PC there is no highscores, we do not have e-peen contest, we just play for fun :)
