Some time ago, somebody here mentioned a winning bidder who was actually an intermediary between buyers in Asia, if I remember correctly. I can't find the post, but perhaps some of you might remember this? Perhaps if the buyer is actually a service buying items on behalf of others, this might explain having feedback of almost 60,000. Just a theory.
That was me. This is the buyer, with over 36,000 feedback points, and that name is one of 7 or 8 used by the company.
