If the student is posting things on their own social media the school should not get involved, the only time they should get involved is if they are posting illegal things on it that the student did on school grounds
EX: smoking, drinking, cheating.
also if the school finds out that the student is posting inappropriate things like borderline p*rnography then they should get involved in the way of contacting a parent. i do not think that the school should be able to censor anything on someones social media.
the school should not get involved with things happening off of the school grounds like smoking or drinking because that is the students life and the parents might let them do it.
