There's a lot of "spite" bidding in collector's circles so having one's identity concealed keeps an individual from engaging in a "take that" game in the auction. It can be seen in live auctions as well, we will often note individuals with a stealth bidder in the gallery to separate their identity from competitors observations.
Often times - the spoiler has no interest in acquiring the item, rather, merely wants to sport queer your play. It's been my sincere pleasure to spike them back in the past and stick them with the item... This after reaching my preconceived limit but playing my enthusiasm out to the very end of my line. Kinda ends up with a poker - bluff/raise, sorta vibe.
