I personally think I can tell KJ's style distinctive writing style, regardless of what handle he uses on either Board. Stronger narrative flow. Reads like a fiction novel. He also does a very good job of capturing a given ladies strong points and core personality virtues (the identified "sweet ladies" are indeed sweet, eg Thai Jenny at JR, etc.).
I think the promo part comes in on secondary but important features such as age. But all "venders" do that. For example, I was just reading someone on TERB being very pissed off that a major in-house asian agency was not providing accurate ages for its SPs. In civilian life, I find ladies also often lie about their ages; and I guess the same continues in the spa world. So I am not waiting for anyone to tell me Rita's real age at LM; I will just have to make my own gut assessment if she turns my crank or not. That is the key bottom line issue for every gent in any event.
PS: I strongly disagree with the underlying supposition of the OP that there is one master shiller. Someone who writes like Leviathan has being poking someone who writes like KJ in the butt for several years now on two boards, so it is most logical to conclude they are indeed two different people I would submit.
