Although I don't like Trots usual line, you gain nothing by snitching them to your campus administration. And if you do, it will make things not just worse for them, but also for any other organization in campus. Don't spend your time thinking on how to make life hell for trots and other groups, think about how you advance the movement. If you want to do something productive, find out other students in your uni and create a cell to study ML texts, until you have a big enough team to do other kinds of political work.
Honestly, I find the sectarian attitude of some comrades to be pretty disgusting. I'm not against using polemics to criticize a political line, but another thing is to sabotage other comrades out of pettiness. If that is your attitude I'll stop calling you comrade, and you will be my enemy instead.
