All wikis are 13+. It is stated in the Wikia terms of use...

"You confirm that you are of legal age to form a binding contract with the Company, or an emancipated minor, or have parental or legal guardian consent and are fully able and competent to enter into, and comply with, these Terms of Use. In any case, you confirm that you are over the age of 13, and acknowledge that the Service is not intended for children under 13 years of age. You may not use the Service and may not accept the Terms of Use if you by law are barred from using the Service or accepting the Terms of Use."

Most wikis do not enforce this, however. We do, although we still keep our content kid-friendly as under 13 users still have permissions to read.
