I think the Backer Cards are what led to his downfall, haha. Even on the positive reviews you can tell he was past his breaking point:
Positive Review
Buyer: "excellent ebay seller, item just as described, perfect, fast shipping A++++++"
Seller: "THANK YOU WISH EVERYONE WOULD READ THE DESCRIPTIONS BUT I GET BLAMED"
I can just hear his yelling these replies in that voice, haha - "STOP! STOP! STOP!"
