Many systems do. In the US, people advocating for mandatory sentencing say the same thing about the justice system, and the RIAA and the MPAA say the same thing about the DMCA safe harbor and takedown notice provisions. Outside of getting google to enforce sanctions against whatever "black hat SEO" methods were used, asking Google to act in that case would appear to be asking Google to settle on a single notion of the limits of free speech and defamation when entire countries of people clearly cannot. I'm not sure putting Google in charge of that is a good idea. (With this sort of thing you start to see why country-specific censorship occurs and may be the best of a set of terrible solutions. See also "the right to forget" vs US court decisions on free speech that is only going to come up more and more)
