Something I left out of my initial post that I wish now I hadn't is this point about what Scott Moore was saying regarding what he heard on John Bond's tapes.
If it is true that Cam Newton knew about his father trying to sell his services, it doesn't mean Auburn did anything wrong throughout the whole process. School officials could really only rely on what Cam and his father told them, as I haven't seen anything to indicate that anyone at Auburn ever got a copy of Bond's and Bill Bell's recordings. If the Newtons lied to the school about everything, then I'm not really sure how it would know or have done anything different.
That said, Cam not knowing about his father's attempted pay-for-play scheme was the basis for him being found eligible for the 2010 season. The NCAA's vice president of academic and membership affairs Kevin Lennon said at the time of reinstatement:
"Based on the information available to the reinstatement staff at this time, we do not have sufficient evidence that Cam Newton or anyone from Auburn was aware of this activity, which led to his reinstatement. From a student-athlete reinstatement perspective, Auburn University met its obligation. ... Under this threshold, the student-athlete has not participated while ineligible."
Cam not knowing absolved Cam. Auburn not knowing absolved Auburn.
If Cam Newton did know, however, he'd be ineligible for the season. Cam knowing doesn't mean his family received any money from anyone. Cam knowing doesn't mean Auburn knew anything or paid anything. Cam knowing does make him ineligible though, as it would make him a party to the money requesting scheme.
In short, Cam knowing doesn't mean Auburn did anything wrong or will face sanctions, but it almost certainly means 0-14.
