It was introduced a few years ago, if my memory's right (definitely hasn't been there since Wikia started), but it doesn't show up in settings on a wiki that has had anonymous editing disabled due to COPPA.

It's possible if your wiki is a subject that could be considered geared toward children and you previously had no anons and no setting but now you have a setting, maybe your wiki is no longer COPPA-reason disabled? *confused shrug*
