Part of the discussion here should also be what privacy is and what it means to other people.
I think that if you are saying something is private the only way that it should be able to be revealed is if all people involved agree to it. Otherwise it's just hidden but can be shown. The old spy adage "Any 2 people can keep a secret so long as one of them is dead" comes into play here.
To others privacy just means it can't be found out by outsiders but anyone involved can reveal it.
To others it means that it can never be shown. It's done it happened but you can't prove it.

I'm stealing that line from you for future use.
