Ok I'm repeating a post because it identically fits this guy as well. Copied from another thread:

OK seriously guys? That's an obvious glitcher. Just looking at it at a glance, at 6th prestige if he even had 2 full days of 2xp left I would be raising an eyebrow about this one.

Let me break it down for you...

He is a prestige 6. So that means with legitimate prestige tokens in mw3, he would have 12 hours of 2xp.

If he had prestiged in the last 4 COD games as well, he would have had an additional 4 tokens for an additional 8 hours of 2xp.

Again, this is assuming he only used prestige tokens for 2xp and nothing else such as unlock gear.

Let's also assume he registered for elite and downloaded the app for XBL, and got 2 hours 2xp that way.

So we are at a total of 22 hours 2xp so far.

He is not a premium Elite member, so did not get the 2hours of 2xp and a free prestige token for christmas. (A total of 4 hr 2xp for Christmas for premium members again assuming 2xp usage for token). So we will assume nothing here.

He is not in a clan, so he is not gaining 2xp from clan rankup. I don't know of any clans that have hit level 20 yet, so say he HAD been in a clan that he is no longer in, and had hit level 10 with then and got a free 2 hours 2xp. We will assume that.

That's 24 hours 2xp. 1 day.

Let's say he also went out and maxed out his 2xp through the Doritos/Mountain Dew promotion, for the full additional 24 hours 2xp. (which I did, and I am a prestige 5 and have already gone through all of my XP for Elite, Doritos, 2 tokens... and have 0 hours 2xp left just playing through level 55 of 5th prestige).

So that's 48 hours total, 2 full days. The maximum he likely could have received LEGITIMATELY as things stand.

So at 2 days, let's PRETEND he was in a clan that hit level 20 that he foolishly quit, for an additional 4 hours 2xp.

And let's PRETEND he was a premium member of Elite, and got those 4 additional hours for Christmas also, and he just for some reason deactivated since then.

So even in pretend-land, he could have at most legitimately gotten 56 hours (2 days and 8 hours) of 2xp.

Let's even it out to 60 hours just in case i missed 4 hours somewhere.  2 days, 12 hours. 2.5 days. maximum, pretendland, just in case i missed something, that this could be legitimate.

I myself had 24 hours through Doritos promotion, 2 for elite app, and 4 for prestige tokens. For a total of 30 hours. And it is GONE just from playing. I'd say i've played almost 2 fullprestiges without any 2xp at all, just guesstimating. That's 1 day and 6 hours drained.

And someone is going to try and tell me that they're a 6th prestige, and after using up a chunk of 2xp time just getting to 6th prestige, that they STILL have 9 DAYS and 8 hours left???

LOL. Not legitimately. Negative prestige token glitch, obviously.
