Given the site’s domain, trollaxor, and the fact that you simply can’t do that kind of stuff in AppleScript, I’d say it’s a joke. If nothing else, he’d need the AppleScript runtime, which is built on the OS sitting on the kernel, so there’s definitely a few layers of recursive turtles involved.
Call me skeptical. Very.
