I suggest you read what is posted inside. To sum it up, all it says is that you shouldn't collect personal information from underage users. Or rather users who self-report as under 13(since there is no way wikia can verify user age) It doesn't say how you should do it.

Wikia chosen method to comply, is by bouncing self-report underage user through the user creation process, where they agree to the terms of use. However, this could have been achieved by various other methods such as the one above and or content like notices where you agree that you are 13... all of which doesn't effect as much the more mature audiance on those wikias.
