I usually go a little harder with it. Suggest they strip down and walk down the street in the buff, or offer to look in their windows at night without them knowing. It’s amazing how people forget that “modesty” is another form of privacy. The issue is that people have a visceral understanding of what a violation of their direct privacy is and what it means, but their virtual privacy, they don’t understand the danger, not the implications of it being taken. Make them feel violated and them get them to equate the two feelings.
