I can build a detailed pro file on you in seconds. All I need is your name and the state you live in.
I’ve seen European ads, where a fortune teller, in a tent, offers to read your fortune. While he’s asking basic questions. In a nearby hotel room, they show a bunch of guys with computers building a profile of this person. By the end of the one minute commercial, they have 30 page dossier of the person who got their fortune read and their given the dossier and told to pick their mouths off the floor.
