Blizz doesn't give a shit about "abuse" for outdated content. Though Naxx may be from this expansion, it's far from relevant content. The guild that got banned for abuse was doing so in ICC... big difference.
That being said. We really didn't need another Jider vid wasting space on the front page. I mean... really... all he does is his little back and forth thing for the most part, as well as demonstrate that he has way too much time on his hands.
