Basically, the thing that I'm worried about is being banned for marketplace theft which results in a 9999 ban of the account and a console ban (I think?). The only thing I've done so far is use Gamer Picture Injector to change my gamer pic a few times for a little while and then change it back to this one Fallout 3 Picture that I actually purchased from the marketplace. I have over a 1000 Gamer Pictures saved on a USB Stick but I never ever transferred them over the the Xbox 360 Hard drive, they always stayed on the stick. Do they have some sort of tracking system that keeps record of whenever you changed your gamer picture and what you changed it to and the date or something? I don't really mod and it would be absolutely dreadful to be banned over that.
