Demotion(On Live) in Call of Duty: World at War

[Fish]

 So my little brothers get on CoD: WW and get on Live. Before they were level 65 (highest w/out prestige) and when they got on they were demoted back to level 1. Not 1st prestige level one, but no prestige level one. On the Barracks' leader boards it has them last recorded as level 65.

So why'd Treyarch demoted them? Is it some glitch or is there some other reason?
Thanks & Happy New Year.

Were they cheating or playing with cheaters?

Treyarch said they were going to crack down on turbo controller users to make it more fair, so I guess they are targeting people who leveled up really quick.

 The weren't cheating or glitching and we don't have a Turbo Controller.
I have checked out Treyarch's message boards and found a lot of other people who have been demoted. They're demoting people who have been reported. So if some little kid thinks you're modding or something and you aren't or a person doesn't like you and gets a bunch of people the report then you're screwed. Treyarch is a blind man with a gun shooting at anyone who sounds like they're doing wrong. >.>
