To have ongoing conversations with their kids.
I have a friend whose son had a file with all the nudes from the local high schools saved. He was selling them. Quite the entrepreneur. When I found out about it I immediately went to face to face visit with my friend about the trouble his son was messing with.
The kid was about to turn 18 and most of the images were of minors. I think my buddy shut that business down real quick. I say “I think” because he thinks he did but who knows with cloud storage and all that. The kid is now 25 and is a good citizen so it appears he left that monkey business behind him.
