Hey, I was advised to ask you guys here at thetechgame about my problem so I hope this topic is okay here.

tl;dr - I would like all my challenges reset.

During the big surge of hacked lobbies earlier this year, my account was hacked up to 9th and then 10th prestige, after reaching 8th prestige legitimately. All my challenges were auto-completed and my stats were ruined too.

Soon after this I jb'd my PS3 and got the hacks myself -- mainly just so I could host normal games for my mates without other people hacking 24/7. This was pretty cool but of course I went clean when Sony went ape-shit. I seem to recall among the reams of options within the various menus, there was a 'De-rank' ability. I never used it so I'm not exactly sure how it would work, but there still seems to be quite a bit of hacking going on here and there, even since the patch, right? So I was wondering if there is anybody out there who would be able to de-rank me down to 9th prestige so that my challenges could be reset.

I still play MW2 daily, even though I have absolutely nothing to play for any more (10th prestige; 100% campaign; 100% spec ops; Platinum trophy). All I want is to have the chance to complete all the challenges and hidden challenges by myself, as well as the opportunity to be able to say I reached 10th prestige legit. Can you help?
