Yes, I got a little confused between fattydash and FatFreddy88 at first, but I think the "feel" of them is different (plus, I believe FF88 has been around JREF for some time).
I don't think Patrick is a troll in the sense that he is making things up *solely* for attention. I think he likes the fantasy of being a top investigator/doctor/bicyclist/what's next, and if he knows, deep down, that he's not one, he tells himself he's "as good as they are, even if I don't have the degree". His ego is such that he really believes that he has found proof of fraud, even if he knows he plays fast and loose with his evidence and credentials. It's fascinating, and a little sad.
