Yes. But No. But Yes. But No. But Yes. Hang on a minute I'll just go and Google and then give my answer................
Seriously though (yeah right!), I think Hugh/Chris came close recently to exposing who Codprawn is:
You set up a website. It's dedicated to a sub-species of an existing sport.
You get some hits, but not as many as you'd like and certainly not enough to inspire confidence with your sponsors. So what do you do?
You invent someone.
A member who posts frequently.
Someone who provokes responses and lengthy debates.
As time goes by the character develops, helped of course, by all the responses provoked.
Within a few months the character becomes an embedded part of the site culture: people "tune-in" just to read the next instalment of the saga.
Et voila! Your site has a healthy traffic count. Sponsors are happy, you're happy, the host provider is happy, the clients are happy.
ergo: JK is Codprawn, Quod Erat Demonstrandum and thank you
of course I could be wrong, but that's what Google says
