It's the big brother mentality that most fear.
JWill talked about it pretty extensively multiple times. It's the idea of always looking over your back worried you may be doing something wrong and someone is willing to report you. And it's not crazy stuff like sleeping with the ladies, ect. It simply having them in your room on the wrong day crap.
The other thing is the fact that if there is a slip up will losing a season because you get suspended worth it?
