There is method to Jagex's madness :) The Children's Online Privacy Protection Act (COPPA)1 is a United States federal law, forming Chapter 15, Section 6501, of the United States Code. The act, effective April 21, 2000, applies to the online collection of personal information by persons or entities under U.S. jurisdiction from children under 13 years of age. It details what a website operator must include in a privacy policy, when and how to seek verifiable consent from a parent or guardian, and what responsibilities an operator has to protect children's privacy and safety online including restrictions on the marketing to those under 13. Similar laws exist in other countries. Ostensibly because of the cost incurred in complying with the regulation, one of COPPA's largest impacts was to cause a number of websites that catered to children to shut down entirely even though the required website structure to comply with COPPA is relatively light. A number of other general-audience websites stopped offering services to children at all. There has been little actual legal action taken against a website operator for COPPA violations. Much of the time, people under 13 years of age simply create a fake identity or lie about their age for use on these websites. Taken from http://en.wikipedia.org/wiki/COPPA Basically Jagex have a legal responsibility to do this. :P Its been around for a fair old time.
