I lost a bid for some transistors with long leads. I then got an email from ebay, "Item not won, similar items found.." and it gave the following auction, "3,29,337 Quailty Email Leads!!"(sic) (see URL below). Obviously this is a spammer illegally selling email addresses. So I reported it, but I went thru the steps and found no specific prohibition against this in ebay's spam policy, or in answers, or FAQs. I left a question for more info on a discussion forum.
Later I went back to see if it was still there, and guess what?! It is not! Yess! Got 'em! Dirty little parasite!
