he basically HAS removed all his items, he's stuck with exclusives left guys. I checked his inventory when he made the post, at the time he had only two items he could rid of. He still only has two items that are sellable.
Also dude if you don't want to refund the game, but don't play it. you don't need to clear your inventory because of it. Or you could just actually refund it, do what you like really.
