For a start, prevention. I'm not supporting the distribution of these but why would you want to film a sex tape or take nude photos? And even if you do, at least be certain that both parties or yourself will not leak it out. The people who film or in it have to take some blame for sure, if you didn't film, it wouldn't be leaked at all. Look at those hollywood stars with leaked videos, if you don't do it, there will be no such videos.

Same goes for those daring enough to do in the staircase or carpark, you risk yourself getting caught by the police and/or someone filming you. The toilet would have been 'safer'. So if anything that ex is the main culprit, imo worse than those who actually spread the video.

As for those upskirts, you can wear whatever you like, just don't go overboard, if you know what I mean, and be cautious of your surroundings.
