Trust me, we've passed plenty of this stuff on. UM is well-aware of what its competitors are doing and they've advised the NCAA of same.
The problem is: (1) it's hard to prove; and (2) the NCAA is in bed with the SEC. Everyone in the business knows the biggest crooks are at LSU, and that's where Emmert made his name.
Serious question, why don't you pass on what you know to a site like Deadspin or Gawker, someone with a history of blowing the lids of **** like this. They don't have any vested interest in it other than site hits, so the more devious the plots the better. They could get the dirt on almost anything. If this site, or its contributers want to make a name and try to combat this, thats the way I would go.
Those sites like to have proof as well.
