It does look kind of similar, a***5, then a***n, g***8, o***0 or whatever it was. But lots of people use their name with a number because they can't be bothered to make up something else. And I don't think the stars represent the exact amount of letters hidden.
No what i was getting at by asking welovelouie if she thought bidders letter***letter were shiller is because they are not. Ebay put the stars there so you cant see the bidders id name!
