As a USC student, I know for a fact that USC denied them of everything. USC did not support their filming and they were not allowed to film on any USC-owned property. They weren't supposed to mention the school's name, either (though it will leak out), and I'm kinda surprised that MTV followed that rule.
It was a gigantic mess of drama last semester and I'm interested to see how it plays out. I'm not exactly sure what MTV will show since they weren't allowed anywhere on campus or any campus owned area surrounding it. Could be a lot of the girls just sitting in their houses... who knows.
I actually just looked at the bios of MTV and one of the girls was in my Spanish class! She was cool.
