Sorry, but there's nothing in the OP that changes the fact that this is none of the NCAA's business and they're still overstepping their bounds and punishing innocent people.
Imagine if one of the people running this fine blog were found to be guilty of the crimes that Sandusky was convicted of, and other people running it were covering it up. Now, imagine Red Berenson deciding that, as punishment, all members of this blog lose access to the internet forever. That's essentially what happened here. Not only is the Sandusky scandal not in the viscinity of the NCAA's jurisdiction(for many reasons), but the punishment doesn't come close to fitting the crime...because they're not punishing ANYBODY who actually committed a crime! If it was found that the people in charge of the blog were actually running a pedophile ring, would that make it acceptable for Red to ban all members of the blog forever? Of course not. Obviously, legally and morally, the latest developments at Penn State make things far worse and far more difficult to stomach. But as far as the NCAA's involvement, this changes nothing, because it still has nothing to do with them.
If it turns out the pedophile ring included recruits who were drawn to Penn State because of the access they'd have to little boys, or if it included coaches or players on other teams who were throwing games because they were given access to little boys...then we can talk. Because at that point, unlike right now, NCAA rules would have been broken. Unlike right now, they'd have grounds to punish Penn State, and hopefully they would permanently shut down the football program.
I know this will be an unpopular statement, but that's often the case for cold, hard facts.
