Priceline is a publically traded company that makes specific claims about its mode of operation and sets out rules in its terms of service. Their reports detail the proprietary nature of their business and the sanctity of their business model. It is inconceivable that Priceline will not take action if someone is infiltrating their database. They would not take action until they gather enough evidence and show that the actions are damaging their business and their reputation. Priceline's ability to make money from the bidding model is precluded on the assumption that customers will over-bid and Priceline, not the hotel, will keep the difference. In the extreme, if all customers were lost to those who claim to have infiltrated their system, it would make them less competitive. Effectively, they would turn into Hotwire since there would be no need to request a bid if the price is accessible in advance. Priceline may be watching to see what is going on and if its system has been compromised or if an entrpreneur is merely taking guesses. In either case, given Priceline's history of lawsuits and victories, both the vendor and customer involved in a bid by infiltration should be aware of the potential problem.
