I think the problem Ebay and any other online selling place has is that it's an automated business so they have to use code to search and weed out scammers. They'll certainly pull any adverts when you complain about them but otherwise they don't have a realistic monitoring system in place. There have been a series of very, very, very cheap Elans on Ebay UK recently, the guys on Lotuselan.net forum complain and the ad gets pulled almost daily it would seem.
But for a determined scammer, it's easy enough to create a new online ID, new Ebay account and away they go. What Alex and no doubt other victims of this guy have been through is quite chilling and I'm really struggling to understand just why law enforcement aren't flattening the guy. There's past history, proof of correspondence, money transfer and nothing for car transport - slam dunk in anyone's book.
