ebay is full of these clowns nowadays. All it takes is one 'sucker' to bite. I'm quite sure the seller isn't stupid. This is a straight on hustle being perpetrated. There likely isn't a 'rube' around to bite, as most fools have already been parted from their money due to the worldwide economy..
But it's like fishing.. Throw a few hooks in the water. At those prices, you only need one bite.
I'm quite sure the user has had ID's before, and deserted them when some duped buyer started leaving nasty feedback.
Gotta admit though, I got a good laugh looking at some of his/her auctions. Remind me of my favorite ever, from about 10 years ago - somebody listed a used 10 cent Jefferson Memorial (sc #1510), common as dishwater as a general use stamp back in the 70s - as a rarity with a minimum bid of $500..
... and it sold.
