How do we know so much about this guy? We know his name, where he's from, his level of education, where he lives, what he looks like. Is some much of his life on the web? How much of it or any of it really him? Why do we care?
Someone else kind of explained it, but I'll give some more backstory on pantherhawk.
He has been trolling the Gophers for years and eventually people started looking up stuff on him. Well, it turns out that he had a myspace page years ago and on that page, all of this stuff really existed:
(1) Him playing with lightsabers
(2) Him flirting with obese women
(3) Him playing the saxophone in front of a a crooked picture of Dallas Clark in a dingy basement.
(4) Tons of Star Wars references
Now, other people did some searching under his myspace screen name and found that he literally was on Harry Potter Fansites talking about crying as he was reading the books. It was all confirmed by other Hawkeye posters who know who he is and he admitted to all of these things.
His new schtick is that he poses as pretty girls on facebook to tell recruits how bad the U of MN is.
All of this is 100% true, that really is Pantherhawk.
