A year and a half ago I broke up with my ex, I was stupidly obsessed with him, the first 10 months I spent under a black cloud trying to accept that he never loved me and that everyone was right when they said that he only loved me because he knew he could get money from me, time passed and I recovered emotionally and for months I hadn't thought about him, I wasn't interested but...

A few days ago I discovered that he is part of a group on social networks in which they publish intimate photos and videos of many women among whom I was, he shared my photos and videos, the ones that I sent him while we were together and the ones that he recorded without my consent, but it was not just me, there were more women, many who were with him and they are not only the intimate photos but they also left screenshots of the social media profiles of many of them.

I know that his mother is aware of everything and she has a lot of influence and contacts so I don't know whether to report it or not, I don't know if it will help or I will just make a dangerous enemy, I admit that it makes me helpless to know that this is already a pattern of behavior and any woman who crosses paths with him will end up the same as me and the same as all of us who are already there, however I don't know how to act.

Any advice?
