Internet Filtering(CENSORSHIP)

Internet censorship is the control or suppression of the publishing of, or access to information on the Internet. It may be carried out by governments or by private organizations at the behest of government, regulators, or on their own initiative. Individuals and organizations may engage in self-censorship for moral, religious, or business reasons, to conform to societal norms, due to intimidation, or out of fear of legal or other consequences.
Opinions on the topic of Internet censorship vary, with arguments being made both for and against censorship. Moreover, the extent of Internet censorship varies on a country-to-country basis. While some countries have little Internet censorship, other countries go as far as to limit the access of information such as news and suppress discussion among citizens. Internet censorship also occurs in response to or in anticipation of events such as elections, protests, and riots. An example is the increased censorship due to the events of the Arab Spring.
