How much % is it to get banned using Prestige/level hack with change time played?
Well it is around 0%, if you use it properly,
Use while in the barracks, don't jump to 10th prestige level 70 without editing your kills/deathss etc, and it should be fine.
/marked as solved
No problem at all, because its not like that much of an "dangerous" cheat to the community.
