Linda,
Looking in the ID history the person has been a eBayer for sometime, yet just recently changed ID, unfortunately eBay does not allow checks on the old ID, or at least that is the impression I get.
I have "heard" of some sellers having more than 1 identity and dummy bidding to boost their returns from the auction. Wether or not it happens is only conjecture.....
