Hi there. Were you seeing some of this information on the website that "ranks" fraternities and sororities? I would certainly advise pnms to avoid that site which does draw in trolls who like to stir up trouble.
I took a quick look at their Fraternity and Sorority Life page and there is a statement regarding hazing there.

The university's Panhellenic will likely address what is hazing, the NPC's policy on it and more during recruitment orientation.
