I Dont't Know What to Do

Alright, I came across a comment on social media by someone I used to club with back in the 90s. We weren't close but we ran in the same circles. It was a photo of him with a mustache and someone had made a comment about a 12 year old being on his lip. The guy I knew back then commented saying he wishes. I don't know if I should screenshot it and report it or how to even address that. His profile is private so only a select amount of people can see it and I can see it. I don't remember him doing any shady business back in the day but what do I know I was too drunk and drugged out to remember much anyway.

As someone who had a few run ins with older men with bad intentions when I was much much younger that comment freaked me out. Part of me feels I need to do something and another part says this is bigger than you don't get involved this is how people get "whacked".
