That's partially right. Over time, people have found the names of well known bidders through feedback on old auctions and you can use them in the advanced search on Ebay to track what that bidder is currently bidding on. For anyone that finds gems by exploiting listing mistakes or things that are not fully described in the auction description, it means that they have to wait until the very end to avoid drawing attention to their finds.
