I've noticed there seems to be more and more of the stuff that's been banned from eBay filtering it's way down to local auctions, storefront type web sites, etc.
It's going to be a long time before this junk is removed from the market. Sadly, someone took a bath on it and is looking to pass the hot potato.
It's a bitter pill to swallow, but you have to do it. I recently ran some signed photos through a shredder. All I could envision is that I was shredding a stack of $20 bills.
