Ethiopian Shim Sham

Does anyone remember History of the World, Part 1? An eBayer has shammed me. I sold an item to someone who's claimed not to have received the item. Because of my ignorace of eBay savvy, I shipped the item sans tracking information, so I have no way to verify the delivery. I did take out insurance, but that does not seem to be good enough. Should I reveal the identity of this scammer? Probably not. I suppose in the grand scheme of things, it was I that was at fault for allowing him to take advantage of me. Depressing? Not really. It was an expensive lesson.
