I have also come across these Open Office ebay listings and ran into the same problems you have outlined when trying to report the seller - there is no proper category for the infringement. And as far as calling ebay goes - good luck! Their phone number is nearly impossible to find and, from what I've read, even if you do find it their agents are often rude and unaccommodating. It seems like ebay is going to hell lately as it's becoming flooded with scammers and crooks, posing as both sellers and buyers.
