I attend BYU and didn't see or hear anything like this. I had a friend that worked for the Student Review always looking for players that broke rules....
First off, there is no HC police. Also, ratting HC rule-breakers is generally false. You don't get kicked out for breaking basic LDS rules unless it becomes routine (drinking every weekend....). Half the stuff uu fans 'know' about BYU is actually false or made up. This post has that made up feel.
