Without a totally Orwellian system to deal with this, how could a university respond in this case? I can sort of see where you're coming from, but there's no clear-cut solution that would be in the university's power. It might be their job to protect students from harassment on Facebook (and I would say even that is slightly extreme), but I cannot fathom how a university could even begin to approach monitoring Yik Yak. Would all students be forced to hand in their cell phones and decrypt all their data? Or should we just set up surveillance cameras in their rooms so we can see when they use their phones? Yes, there are reasons for universities to protect their students, but there is clearly a line to be drawn in this specific case.
