What.cd was pretty well known. It had a large userbase and items were leaked on there that made international news. A radiohead song was leaked before it was released, rumored to have been done by the band. COFEE a forensics tool made by Microsoft for law enforcement was leaked. And unpublished stories by JD Salinger that were forbidden to be publicly released until 50 years after his death were also leaked. So the site has definitely gotten a lot of publicity.
