is there a way to bring it to ebay's attention so that they can prevent a scam? I am sure ebay just doesn't want a hindsight of 20/20 in their auctions. If you can present a clear case, they will shut down the auction because of false information (just like they do when someone claims a cheap replica as a real thing, and it's proven wrong by someone with credentials they WILL shut it down and ban the user)

Anyways, you might see if you can present it to ebay. If this thing goes for a lot, this could be a really huge scam, and this could mean that if this is on purpose, he may be doing more of these.
