A checkbox or button like this has been specifically called out by the Federal Trade Commission as being insufficient. The FTC said:


 * "Avoiding encouraging children to falsify their age information, for example, by stating that visitors under 13 cannot participate or should ask their parents before participating. In addition, simply including a check box stating, “I am over 12 years old” would not be considered a neutral age-screening mechanism."
