it depend what hack.
Normally, after you close the game & the cheat, it shouldn't let "trace".
But well, if you add to yourself 100.000 token, be sure it's spotted.
And more, VAC (which isn't activated for BO3 atm) scan your disk, searching malicious program.
So just remember.
Don't be ovbious.
Act & play like there was somebody behind you all the time, finger on "ban" button.
Don't cheat on an account you can't afford to loose
