yes it is true I got deranked by a hack and am like millions -xp, so I call xbox to try and get my xp strait and they tell me they can't fix it and tell me to call activision. So I call activision, they pull up my acct. And can see were I all of a sudden get millions of neg. xp in a match but they tell me sorry there is nothing we can do, you should prolly just start a new profile, and this is were I fning lose it, they sit there and tell me ya we know you got screwed but there's nothing we can do to help you. I can't believe there fix is forme to pay for another xbl gold acct. And start all over after I have had this profile for over 3 years with over 30,000 gamer score plus all the download content I have paid for over them years. So I guess what I am getting around to saying is BE VERY CAREFULL of what game invites you accept and of the ppl that you add to you friends list, because if you get into a lobby were someone is deranking ppl. There is no fix for it other than playing for almost ever just to get back to 0 xp, or going into a xp lobby and taking a chance of getting banned for just trying to get back to were you can level up again. And I was also told by activision that ppl are getting deranked by the theater, so just a heads up be very carefull of what you accept from anyone that you do not know or trust, or you could end up like me, from 3rd prestige level 46 back to nothing with no chance of leveling up.
