If Parental Control is enabled, the privacy option “Share my game data with community developers” cannot be disabled the user.
And the parent can’t disable it either, because this option is entirely missing in the Parental Control options.
Would be nice if this option is resolved.
The current workaround is to disable Parental Control all together, ask the user to disable the option, and then disable Parental Control again. This is not a very easy procedure, as Blizzard asks for all kind of identification documents to disable parental control (!).
