The Next Tarantino Scripts?

I read an interesting comment on my last post on Quentin Tarantino:

The screenplay of Quentin Tarantino’s Kung Fu movie has been leaked to the internet. It seems to be some sort of Japanese gangster flick. Link

The linked site contains two scripts:

The working title of the first script, a Japanese gangster/Kung Fu film is GREYHOUND. The second Tarantino script is a teenage crime story called HIGH SCHOOL SKY HIGH.

I think that this was spread by the author of the site, as the name of the author is “Rancor”. Does this person really have beef with Q.T., or are the scripts fake? Justin thinks that the scripts might have been put up by an ambitious writer looking to cash in on some publicity through a hoax.
