“All bidders will appear.”
Don’t you have to go to the “bidding history” to find that? If you just look at the “Current Bid” window, you just see the high bid. So, a casual glance, without the “history” might make it look like someone is bidding against himself. Of course if you’re serious, you would check the “history.” Also, doesn’t ebay tell you that you’re the current high bid?
