Pornography rings typically involve the exchange, sale, and viewing of sexual images depicting children of all ages and from all corners of the world. While pornography rings are not a new phenomenon, they have grown aggressively since the advent of the Internet and because of the ability of anonymous distributors, collectors, and viewers to use Web sites hidden in the more shadowy parts of the Internet for the exchange and sale of child sexual images. The costs to global societies worldwide of the harm that is done from this type of criminal behavior are incalculable.
