Birnk403. And before that Proudster Mary. And before that KernCounty. And before that TheSpa. And he's had several more in-between. He still posts regularly as Ordfan on a forum called Airliners which as you can guess is all about flight and aviation, dead giveaway that he's a Purdue fan but that shouldn't come as a shock with his constant anti-IU rhetoric and consistent need to defend Purdue at all costs.
Very real chance he has a social disorder, likely Asperger's, given his persistence and detailed-oriented posts and responses in order to make others feel inferior at any and all cost. Likely lives with or near a guardian and doesn't venture out much into public and avoids as much human interaction as possible. That's my best guess as a former health instructor, but what do I know?
