I believe that the OP of the rank rigging thread posted it because of its relevance to CC. The source of the scrutiny against USC, in this particular instance, was a post on CC.
I do feel that singling USC out on the front page of the website specifically – which gets thousands upon thousands of hits a day – is defamatory and unnecessary.
Though the above posts are yet to ask the admins this explicitly, I will: please remove the USC posting from the CC-talk home page. It is not neutral in nature and does not belong there.
