Achievement Screw up

I just used the achievement unlocker and was fiddling with things, and pressed save after editing one game. Well as it turns out I logged back in and all the stuff I fiddled with was also saved even thought I closed out of my profile several times, and unlocked around 3 k gamerscore for games I haven’t played in years. I then checked my One and the achievements arn’t synced. Can I reverse them? or is the damage already done, and ban inevitable?

If you signed into live with it then there is nothing you can do. If you haven’t delete the profile and recover it.

I did that. Even worse one of the games updated and now I still have the gamer score. GG
