Does NewsBusters know Rubico10's IP?

A pretty good case is being made by The College Politico.

After all of this I really think there are several things we can learn about these screenshots. They are, in fact, from Rubico. They show he is on a NewsBusters post while hacking into Palin’s email. They show that he is NOT using a proxy to view the NewsBuster post. They give us a specific time frame that he was on the NewsBusters post. Those things are important because they mean that NewsBusters, most likely, can figure out if David Kernell (or rather someone from the University of Tennessee, who I would assume is David Kernell) was on that specific post durring that specific time frame. Is it evidence that you could use in court? Certainly not, but is it enough to get one step closer to convincing me and put a clearer focus on Kernell? Absolutely.
