Handbid allows bidders to enter in a DisplayName that will show in place of their paddle number. A bidder has to manually add this, so this is not something that they can do by mistake.
In addition, managers can also add in a displayName for a bidder or edit their displayName from their bidder profile in the auction manager.
DisplayNames are a gamification technique used to drive more friendly competition and bidding behavior. We recommend you let the bidders keep their displayNames unless you strongly feel otherwise. In those cases, you can remove their displayName from the Auction Manager.
