We are to believe from the bold that they originally divined the identity of NCPAC from these minor clues. Baloney! This would only serve as confirmation IF you already knew who you were looking at.
I agree. I think that someone who worked with or otherwise knew Steffen, and suspected that he might post at FR, came to FR, then used his or her knowledge of Steffen to lay the trap. Either MD4Bush knows Steffen, or, got inside info on Steffen from someone who knows him.
