It's not physically harmful per say but if you ever look through Ex porn, it usually has name calling in the title and you often see videos which were meant to be private and were sent to the other person because they were trusted by their partner.

I just find it pretty sad to think that the girl in the video put trust in the guy and then had a betrayal like that. I have private videos and pictures of girls but never in my life would I do such a shitty thing. The girl would have to actively attempt to destroy my everyday life even after a break up for me to even consider making those private videos and pictures public. She'd have to do some psychopathic stuff to actually have me share the private stuff on the internet...
