From what I have been made to understand, it's honestly a lot of small details that were accidentally overlooked that ended up getting Auburn into trouble. For example, problems with the Auburn audiology website.... It was relatively simple things that all added up at once. The main thing is that Auburn audiology has never been on probation before, and considering how seriously everyone is taking the matter, I don't see it happening again anytime soon.
