There’s little doubt that students share information on social media school administrators might find useful. There is some debate over whether—or how—it can be accurately or ethically extracted by software.
Again, going back to utilitarianism, I think that if this software actually will help saves, which effect 100's of people, it should be implemented by the school as long as the students know about it. With those circumstances, I don't really see any negatives to the story, therefore providing great benefit for a lot of people.
