The law doesn't state those under 13 can't create an account, but, instead, that Wikia (and other US companies) can't knowingly collect information (in this case, an IP address) from individuals under 13. Once Wikia is informed that the user is under 13, they must disable their account because at that point they would be knowingly in possession of information from someone under 13.
