Selling Piggy back off the success of Twilight or the Vampires Suck movie w/ vampiresuck.com

I bought this domain last year when the Twilight movies were all the hype, but I never did anything with it. Once I saw a trailer for a movie called Vampires Suck! coming out I threw some quick ads on it and it started making money. Even though Vampires Suck did terribly at the box office, it still gets visitors each day strictly from typing in the domain. I've done no paid ads, no back linking, nothing, so majority, if not all, of the traffic is coming directly from the URL.
