The ticket shown in the photos with this eBay listing is a GIFT ticket. GIFT tickets are the exceedingly rare complimentary tickets issued by the ORG, and - as with all tickets to the event - are not supposed to be sold at a profit.
I've reported the listing to eBay's customer service department, and hope to see the auction pulled in fairly short order.
Un. Fucking. Believable.
EDITED, 1438PDT: Just heard back from Participant Services:
Some of our gift ticket recipients are providing services for us in exchange of tickets or they have won the tickets in a charity raffle and are unable to go to the event. Although we would like them to not sell their tickets, we can't forbid them to.
So caveat emptor. If you're looking to buy a ticket - whether it's on eBay, Craig's List, or anywhere else - ASK QUESTIONS BEFORE YOU COMMIT. Get the serial number and original price of the ticket from the seller and confirm the info with PartiServ. And don't bid over face value.
