I wonder if the fraud is a two way street. Could I just craft a POST request and book what I want? Each of these companies are only allocated a certain amount of inventory so the availability is probably there, especially at the larger hotels Additionally do they float the price and if so can I edit that also in the post request and name my own price? If their interface has a fuzzy relationship to reality than maybe you can fuzz it your way I'm not a criminal but I'm still curious.
