I like this, because it points to addressing user silence with respect to expectation of privacy. Take your idea one step further.<p>Suppose Tor provided a box that users could (optionally) click to affirmatively declare they were using Tor with an expectation of privacy. Maybe this selection could be locally stored in an encrypted form so that users, if they later needed to prove they had an expectation of privacy, could show they had ticked the box declaring that.<p>This could provide an affirmative declaration that the user expected privacy when using Tor. Would that be useful? Thoughts, anyone?
