No, what they do is contact the admin of the site to get the pertinent details.
Most boosters (an inconsistently applied term as determined by a capricious NCAA) that get into trouble are turned in by fans of opposing teams. It's the other teams' fans that scour bulletin boards looking for violations, then convince their school to file a complaint. As a previous poster has said, two thirds of the SEC complaint against UConn was comprised of posts from the Boneyard. It cost UConn hundreds of thousands of dollars to hire a compliance lawyer to respond to the complaint. The program's and university's reputations were hurt - as well as the reputations of unfairly accused players and parents - because a couple posters on the Boneyard couldn't contain their exuberance.
Maybe fans will get away with defying the NCAA rules but why would they put UConn at risk? Remember, Geno's program was turned in for giving French fries to a recruit, for heaven's sake.
DON'T "HELP" UCONN RECRUIT! It's against NCAA rules and the UConn Compliance Office has asked us, the Boneyard specifically, to stay out of the process. This after the great French fry/cardboard sign/phantom trip from Russia to Atlanta/Boneyard bragging fiasco of a few years ago. Don't give the whackadoos (you know who I'm taking about) any ammunition.
