That's a logical leap, I think. I can easily imagine passing private messages through a Bayesian filter to catch "inappropriate" messages, without needing human intervention. But, yes, if you are using a third-party service to communicate in plain-text, there is no such thing as "private."

and define inappropriate. I could be talking about health, sex, relationships, business, inventions, inside jokes and the list of normal appropriate topics that i wouldn't want other people reading goes on.
forget the NSA, why should anyone aside for me and who i'm talking to be able to flag (and likely checked by a human) private messages?
Private messages on facebook are well, not private it seems.
