I've always been skeptical of this guy's site (and him, natch) but I've never really read any critical reviews that have caught him in the sham.
The filmography/girlfriend thing is the most damning evidence I've seen against him, but these are unrelated to the Star Wars information.
What inconsistencies or falshoods exist there?
Admittidly, I've not spent much time reading the bits from his site, but it seems that his "fraudness" versus his "legitness" will be apparent after the release of Ep. III since he made some plotline revalations that I've not seen in other places.
