I can see his history of his skel1ngt0n account. He owns about 75 games. Around 50 of those games have zero achievements, his gamer score is only 4000ish which seems low for how long he's been gaming and how many games he owns. Some of the games in the picture he posted such as portal 2, new Vegas, blood bowl, blops 2, shift, etc dont show up on his game history. Which means he took the packaging off but never booted them up, not even once. Odd no?
I've gotten a few games before release and always got a receipt and i always run the game to make sure it works before tossing the receipt. (I've seen improperly pressed discs before)
IMO considering how many games the OP owns but has never played I would say he's either an ocd collector or a pirate who got banned then ran out to buy a copy of halo 4 to save his account. Usually pirates will download a bunch of games, run them once to see if they work but never actually play them.
Not sure if anyone has brought this up(not going through the entire thread) but it's my 2cents. If the OP is innocent then the situation sucks but there's too much evidence saying otherwise.
