Legal Question in Intellectual Property in California

You have a method of determining a person's sexual promiscuity from a photograph? You are an attorney's dream client. All pictures on facebook are NOT public domain and are copyrighted by someone, usually the photographer. You do not have permission to use any of the pictures, and you could be sued for thousands of dollars for one picture. Therefore, do not use pictures unless 1) you have taken them yourself; 2) you have permission from the copyright holder; or 3) they are U.S. government works, were made before 1900, or are other known public domain material

Bad business idea! Suppose perhaps 25% of the ladies you identify as "promiscuous" are as saintly as nuns, even though to your eyes they look enticing? How many hundreds of angry plaintiffs will you be facing when the suits hit the courts? Yuck-o.
