Do Countries or political parties censor Facebook, or does Facebook censor its self . Censorship of Facebook has happened because of the open nature of Facebook; several countries have interfered with or banned access to it, including Syria, China, Iran, Vietnam and the United Kingdom. Australia Facebook has a total of 10 million users, thats almost half the population. Australia also requires people to state when they sign-up that they are at least 13 years of age. But, because there is currently no way to formally enforce the age limit, in July 2011 Australia began considering giving parents access to their children's pages, requiring proof of age at sign-up, and increasing the age limit to 18.

United Kingdom
In the UK on April 28, 2011, the day before the Wedding of Prince William and Catherine Middleton, a number of politically motivated Facebook groups and pages were removed or suspended from the website as part of a nationwide crackdown on political activity. Most of these groups were mostly concerned with opposition to government spending cuts, and many were used to organize demonstrations in a continuation of the 2010 UK student protests.This coincided with a series of pre-emptive arrests of known activists. Amongst those arrested were a street theater group planning a performance in opposition to the monarchy, whose members included a 66-year-old professor of anthropology,and five people who were in the wrong place at the wrong time dressed as zombies who were drinking tea in Starbucks at the time of the arrests.
