Not sure what kind of maniac would "consume" porn openly at school. In contrast, I doubt most kids will have any such misgivings about social media, especially if not enforced.

Teenagers can be weird and dumb and like to show off. A kid in my class used to pull porn up on the computer connected to the projector if the teacher left the room, just because they thought it was funny.

Back in my HS years, we had a sped student who loved having a wank in the library.
