People actually do this? :-o
I agree with you though Hilander. If someone allows their partner at the time to take nude pictures of them in the assumption that it will stay private, that privacy should be respected. There should be a law preventing people from posting such pics, whether it is done out of revenge or not. If the person in the picture did not agree to it being used anywhere other than in private, it is a violation of their privacy.
That said though, people might want to think more carefully before letting anyone taking nude pictures of them anyway. It's so easy to put pictures all over the web these days, and once it's been put out there, the damage is done. You might hear about something like this from your friends long before you realize it yourself. That's a scary thought.
