Kids get around COPPA all the time. Everyone in my kid's middle school knows that you have to simply lie about your age when you sign up for an Internet service, because most of them won't let you in if you are stupid enough to say you are under 13, and the services that let you in are nerfed to the point of uselessness.

Furthermore, now I have to navigate the morality of encouraging my own kid to lie, just so she can use an online service that I approve of as a parent. Terrible law.
