Because of US COPPA laws, Wikia prohibits any users under the age of 13 from participating. There is a clause in the Terms of Service that states that, by agreeing to the TOS, you are over the age of 13 (Membership section, paragraph 1). Accepting the TOS under the age of 13 can be grounds for immediate termination because of violation of that specific clause.
