The purpose of many of these sites is to extort money from people who have had mugshots taken of them, regardless of whether they are ultimately guilty or innocent, and long after they have since served their time or been found innocent. Imagine you are accused of a crime you did not commit, are arrested and end up in jail long enough to lose your job, are found innocent, but searches for your name come up with your mugshot and outdated information about the crime you never committed... because 10 sites have all decided to make you a part of their list. And you can have your mugshot taken down, if you will agree to pay them $50. Each.
Does this still seem like nothing's wrong here?
