Ebay is a complete robot operated business, and the only way anything is banned or pulled is if something in the listing sets of their system. I can't imagine there is any REAL ban in place, but who the hell knows. I have had many items pulled over the years, and once I changed the wording, I never had another problem.
I agree with Pleng. I'm sure Craig may have just put something in his listing that set off there security system. Maybe someone has reported the Pandora as a piracy device, but like I said, their system sucks ass, and you can't talk to a real person about anything relevent if your life depended on it. I wouldn't sound the alarms just yet.

Edit: Yeah,"Piracy Device" seems like Ebays robot reply system. If games or roms, or something else was listed, there robot just ends the listing, and sends a pre set message. I could list a piece of fruit on ebay, and it could be remove and that same message sent if I put certain key words in. I would reccommend Craig, just relist and leave his description as vague as possible and see what happens.
