this is my first post here so please let me know if this is not the correct forum for this.

A few days back my classmate shared a picture of my mom (her facebook profile picture) on a subreddit for cum tributes, and sent a screenshot to me. After much threatening and requesting I was able to get him to take the post down, but I am scared that he has shared her pictures and/or her personal information elsewhere as well, since she keeps getting calls from unknown numbers daily.

I am actually not sure what to do in this case. Both of us are underage (15 this year), so I am not sure if he can get into legal trouble if I report this. I don't want him to go to jail or anything, I just want him to not do this in the future. I am also unsure if I should let my mom know about this, because if I do then surely the situation will escalate much further, and it is also a bit embarrassing to discuss these things with her in the first place.

Thanks in advance for any help!
