There is no question that some coaches partake in "negative recruiting".
They may not want a recruit, or they may not stand a chance to get him, but they will do whatever they can to make sure their conference rival doesn't get him.
So in that case, it might be a detriment for too much info to be out on a message board about who a coach is recruiting. Most coaches are highly secretive about recruiting info, as well as game-plan info.
