For the past couple weeks I've been investigating used road bikes on Ebay and I have begun to notice that most if not all of the bidders have a name that is similar to one another. If you take a quick look on Ebay you find that all bidders have a username that begins with a letter or a number, followed by two asterisks, then another number or letter. (9**b, y**u, p**1, etc.) Does anyone happen to know what this means? They seem to like to just bid and it gets quite frustrating.
