eBay now hides bidders identity to protect both buyers and sellers. They do this on auctions the feel should be protected. I have had problems in the past with watchers contacting MY BIDDERS and offering them something similar for less than my current auction. Or they actually would say why would you pay that much for that moped........etc. etc.
Get the picture.
I say, Let sellers sell and let buyers buy.
PS I've attached a pic of my 75 Puch with less than 100 miles on it. It's beautiful
