you know, there is a good chance that they will do something. IW isn't that stupid.
Maybe they set up a test or something for this, like once you reach level 1 on a prestige it remembers.
So say you are no prestige and you jump to prestige 2.
IW would know that you hacked/glitched/something because you were never actually on prestige 1, even though you are currently on prestige 2.
Not saying they did this, but they probably set up something to prevent hacking.
