The purpose is to help Hotel Operators determine whether or not they should accept a reservation from certain people or, simply pass. To say that this a new concept would not be true. What's new is the trend to organize and distribute this data among hotels and, perhaps in the future, restaurants. Many hotels now refuse guests based on their perceived or real behaviour. For example many hotels in Florida and the Caribbean will not accept reservations for "Spring Break" groups. In Europe hotels shy away from groups of British Soccer fans.
