Actually, Google is a search engine and therefor, results include all types of websites, even those that are not legit. That is what a search engine basically is and in some places, for instance, China, search engine providers like Yahoo and perhaps even Google, have restrictions on search results. An example of this is in China, if you type in Christianity, it will just shut down your computer.
Bullshit. They can block stuff, but they cannot actually shutdown your computer unless there your system has been majorly compromised by government malware.
