bidonbitcoins.com Suspicion of Bots
The site has been showing suspicious behavior that suggests that an auto-bidding bot or “Sniper Bot” is manipulating the game to push the price so high it goes beyond the price of the bitcoin itself. Here is a link to a photo with typical auction.

Notice the bot is continuing to bid even when its not profitable for the bidder, the only one who profits from that is the site owner.
