Allow me to say that this might be a good thing, as many sorts of peer 
accountability would.

 While _some_ degree of privacy does make _some_ sense, a system that 
would be so "private" that no one but the kid would access might be 
really insecure in real world terms.

It is hard for me to imagine something that a kid _needs_ to hide from 
everyone that would not be a potential danger.

I can imagine pranks (the classic "baggy pants"),

Because I have been professionally trained to foresee all sorts of 
misuse, I can be as paranoid as to kids' safety as the best.

Maybe I take the good of open source peer accountability too seriously...
