China censors both the publishing and viewing of online material. Many controversial events are censored from news coverage, preventing many Chinese citizens from knowing about the actions of their government, and severely restricting freedom of the press. China's censorship includes the complete blockage of various websites, apps, and video games, inspiring the policy's nickname, the Great Firewall of China, which blocks websites. Methods used to block websites and pages include DNS spoofing, blocking access to IP addresses, analyzing and filtering URLs, packet inspection, and resetting connections.

Internet activism involves the use of electronic-communication technologies such as social media, e-mail, and podcasts for various forms of activism to enable faster and more effective communication by citizen movements, the delivery of particular information to large and specific audiences, as well as coordination. Internet technologies are used by activists for cause-related fundraising, community building, lobbying, and organizing. A digital-activism campaign is "an organized public effort, making collective claims on a target authority, in which civic initiators or supporters use digital media." Research has started to address specifically how activist/advocacy groups in the U.S. and in Canada use social media to achieve digital-activism objectives.

Censorship in the People's Republic of China (PRC) is mandated by the country's ruling party, the Chinese Communist Party (CCP). It is one of the strictest censorship regimes in the world. The government censors content for mainly political reasons, such as curtailing political opposition, and censoring events unfavorable to the CCP, such as the 1989 Tiananmen Square protests and massacre, pro-democracy movements in China, the persecution of Uyghurs in China, human rights in Tibet, Falun Gong, pro-democracy protests in Hong Kong, and aspects of the COVID-19 pandemic. Since Xi Jinping became the general secretary of the Chinese Communist Party in 2012, censorship has been "significantly stepped up".
Internet censorship is the legal control or suppression of what can be accessed, published, or viewed on the Internet. Censorship is most often applied to specific internet domains but exceptionally may extend to all Internet resources located outside the jurisdiction of the censoring state. Internet censorship may also put restrictions on what information can be made internet accessible. Organizations providing internet access – such as schools and libraries – may choose to preclude access to material that they consider undesirable, offensive, age-inappropriate or even illegal, and regard this as ethical behavior rather than censorship. Individuals and organizations may engage in self-censorship of material they publish, for moral, religious, or business reasons, to conform to societal norms, political views, due to intimidation, or out of fear of legal or other consequences.
Censorship is the suppression of speech, public communication, or other information. This may be done on the basis that such material is considered objectionable, harmful, sensitive, or "inconvenient". Censorship can be conducted by governments, private institutions. When an individual such as an author or other creator engages in censorship of their own works or speech, it is referred to as self-censorship. General censorship occurs in a variety of different media, including speech, books, music, films, and other arts, the press, radio, television, and the Internet for a variety of claimed reasons including national security, to control obscenity, pornography, and hate speech, to protect children or other vulnerable groups, to promote or restrict political or religious views, and to prevent slander and libel. Specific rules and regulations regarding censorship vary between legal jurisdictions and/or private organizations.
Internet censorship in South Korea is prevalent, and contains some unique elements such as the blocking of pro-North Korea websites, and to a lesser extent, Japanese websites, which led to it being categorized as "pervasive" in the conflict/security area by OpenNet Initiative. South Korea is also one of the few developed countries where pornography is largely illegal, with the exception of social media websites which are a common source of legal pornography in the country. Any and all material deemed "harmful" or subversive by the state is censored. The country also has a "cyber defamation law", which allow the police to crack down on comments deemed "hateful" without any reports from victims, with citizens being sentenced for such offenses.

In the PRC there are criminal laws which prohibit the production, dissemination, and selling of sexually explicit material, and anyone doing so may be sentenced to life imprisonment. There is an ongoing campaign against "spiritual pollution", the term referencing the Chinese Communist party's Anti-Spiritual Pollution Campaign of 1983.

Collateral freedom is an anti-censorship strategy that attempts to make it economically prohibitive for censors to block content on the Internet. This is achieved by hosting content on cloud services that are considered by censors to be "too important to block," and then using encryption to prevent censors from identifying requests for censored information that is hosted among other content, forcing censors to either allow access to the censored information or take down entire services.

Alt-tech is a collection of social networking services and Internet service providers popular among the alt-right, far-right, and others who espouse extremism or fringe theories, typically because they employ looser content moderation than mainstream platforms. The term "alt-tech" is a portmanteau of "alt-right" and "Big Tech". Starting around 2015, some prominent conservatives and their supporters began to use alt-tech platforms because they had been banned from other social media platforms. Alt-tech platforms describe themselves as protectors of free speech and individual liberty, which researchers and journalists have alleged may be a dog whistle for antisemitism and terrorism.
