Protesting is relevant when it occurs towards someone holding an office or a public role/responsibility (even if temporary).
Protesting someone repeatedly or in their private capacity (which is the case for any student at the university): that becomes harassment.
Threatening: that's a whole other level.
And narcing on someone in the hope that whoever you narc'd to then goes on to threaten that person's family or friends elsewhere is another several levels beyond that.
