When I was in high school I had a friend who worked at one of those 1-hr photo processing places. People would bring their film in to have prints made. And there were no small numbers of "intimate" photos on those rolls of film. Yes even in the days of film cameras, people took photos of themselves in sexual situations.
Of course my friend thought it was hilarious and the shop would make extra prints of these photos to pass around among the staff. They had separate categories similar to what you'd see on any porn site. Of course it was in violation of policy but people do this stuff. If you're building something that handles photo/video images you must expect it and build in privacy from the ground up. You cannot rely on your staff to always be on their best behavior.
