You have already been answered and that answer will not change.

This is not an appeal forum and you can not appeal VAC bans.

Saying "You didn't cheat on THIS account" implies you cheated on a different account. Which means you had cheats on your computer that VAC detected.

So the ban is correct and will not be removed ever.

The Steam discussions aren't the appropriate place to dispute specific bans, please read the following FAQ
