An elaboration on this: if they are underage, they lied upon registration. That, per the Terms of Use, is grounds for the account to be disabled.

Because COPPA prohibits Fandom from storing private info of people they know to be under 13, all the personal account info would have to be wiped. And AFAIK, that can't happen on a blocked account, only on a disabled account. That's why the account is disabled instead of blocked until they turn 13.
