2 = possibly wrong, but no action needs to be taken
3 = wrong, and school authorities or internet services provides should take action
4 = wrong, civil action would be taken by the target or the target's parents
5 = wrong, and criminal charges should be pressed
A student posts a negative review of a concert given by another student's band. The review focused on the band members' skill as musicians and the quality of their music.
I think 2 because every negative should include a positive. But if the review is only about their then ok. But if it was something more personal, then not okay
