I found another suspicious ebay seller selling similar items, so I checked their "member since...." date. Guess what? Exactly the same date as the scammer that had disappeared from ebay after scamming me and others! This one also has some 200 feedback. I bet with reasonable confidence that it's the same person/group. I think their pattern is, register mulltiple accounts on the same day (or within a span of few days), have some legitimate sales to get positive feedbacks, then after a year or so, abruptly disappear into thin air after many buyers paid for their winning bids. Apparently they are in China.
