To all that wonder.
Changing your name won't do any good

People will still be able to find you if they want to.
Because they can only look on the last match. (If you think about reports.)
But still, bans do scan Memory editing for most of time.
Means even if you change your name you won't be safe.
Your steam account have an ID and an account Name.
(The Name is when you log in to steam.)
So this is kinda not helpful.
Also, the scans...
I think they run 24/7.
Because it's just an "engine" that search for memory changes and so.
And that is why most that create and release hacks that is related to Stats and so, tell you to use them in the Barracks and not in the game.
Because VAC is NOT scanning in the Barracks. (After last update info given.)
