Are there trademark infringement issues here, particular on Google's part? They are getting paid (probably a lot) to display this ad, and are explicitly allowing buyers to lie about their identity.
If I were eBay, I'd be getting my lawyers on this immediately. Every dollar getting paid to Google for this ad is a dollar out of my revenue, and a lost customer, and is illegal.
And eBay will be made responsible for damages. "I click on that ebay ad and then my computer was locked down and a hacker said I need to pay him to get my files back".
