This discussion is going wildly off-thread here, but although you could argue that in the eye of the law, the result is still the same, there are some differences between the "start-struck" teenager setting their sights on a celebrity & an adult deliberately setting out to groom/abuse a youth.
....you would think so, but youth of today think that they are cleverer. They get told about CEOP & rapidly forget it. Very recently, a local "young adult" was sentenced for blackmailing a young girl into sending him naked pictures. He had set up a false (under18) profile on social media & asked numerous young girls for juicy photos. At least 2 girls did so, & he then blackmailed one to send more photos. She didn't so he posted the original photos to her friends on the social media group.
"Digital permanence" doesn't seem to figure with most youngsters; the advice we gave to ours was do not send anything via whatever medium that you would not want your granny to see or hear about! In this case, the person was wrong to ask for such photos in the first place (it is a criminal offence - a lot of teenager are not aware of this) but then this was compounded by what I can only call stupidity of the girls to then send naked pictures.
Most of us are probably guilty of the "look at me" aspects of social media - the trouble is, the internet can be a very dangerous place. Check your cadets' profiles on Facebook - how many of them are completely open??
It's undoubtedly a "generation" issue, but girls seem to develop quicker physically - & more importantly, despite being significantly under 18, want to go places (night clubs, etc) to strut their stuff & generally show off - with or without parental knowledge.
