It's all about optimizing for the search engines nowadays.
People sell malware kits (websites and such) that are SEO'ed to be #1 for whatever product they represent, often luring others into purchasing membership into a forum for help or downloading software that will infect their computer and make them part of a botnet or worse. It's no surprise that a site like that would reach the top.
Two words. Mechanical Turk.

Just becuase a site gets a high position does not mean it will stay there if it is, indeed, crapola on a stick. The wisdom of crowds effect will kick in eventually and the detritis will sink to the bottom while the cream floats to the top. Or at least that's what I hope will happen :)
