An example is the increased censorship due to the events of the Arab Spring.
Other areas of censorship include copyrights, defamation, harassment, and obscene material.
In the same survey 83% agreed that "access to the Internet should be considered a basic human right" and 86% agreed that "freedom of expression should be guaranteed on the Internet".
According to Global Web Index, over 400 million people use virtual private networks to circumvent censorship or for increased user privacy.
Technical censorship techniques are subject to both over- and under-blocking since it is often impossible to always block exactly the targeted content without blocking other permissible material or allowing some access to targeted material and so providing more or less protection than desired.
Thus censors must work to prevent access to information even though they lack physical or legal control over the websites themselves.
This in turn requires the use of technical censorship methods that are unique to the Internet, such as site blocking and content filtering.
Unless the censor has total control over all Internet-connected computers, such as in North Korea (who employ an intranet that only privileged citizens can access), or Cuba, total censorship of information is very difficult or impossible to achieve due to the underlying distributed technology of the Internet.
Pseudonymity and data havens (such as Freenet) protect free speech using technologies that guarantee material cannot be removed and prevents the identification of authors.
Support for and opposition to Internet censorship also varies.
