Thanks to everyone who contact eBay over the last two days! They have announced that they will not allow the auction to take place.
Based on the details we know about the anticipated listings, we believe these would violate our policy regarding offensive material. eBay will not permit the items in question to be posted to the eBay site, and they will be removed if they are posted.
No word yet from Roeder's fellow terrorists if they will try to host the auction someplace else or just blow up eBay for not doing what they want
