It looks like there is some kind of scam going on with brand new bidders who joined eBay 9/20/06-9/22/06 and bid rediculously high on items, such as phones. From what I've seen, these bidders are bidding up phones and using buy it nows with no feedback, winning multiple auctions for the same things, and basically messing up legitimate auctions. Their user IDs usually make no sense and their feedbacks say that they are 'private'.  This seems to be a pretty large-scale scam, which has been based on cell phone auctions from what I've seen. You can check through eBay in completed listings to see where else it might be. I don't know what the point of their scam is, or what their final plan is, but I wouldn't trust them with your email addresses and ESPECIALLY not any of your private information.
