Internet censorship is one of the forms of censorship, the suppression of speech, public communication and other information. The People's Republic of China (PRC) 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.
The government blocks website content and monitors Internet access. As required by the government, major Internet platforms in China have established elaborate self-censorship mechanisms. Internet platforms are required to implement a real-name system, requiring users' real names, ID numbers, and other information when providing services. As of 2019, more than sixty online restrictions had been created by the Government of China and implemented by provincial branches of state-owned ISPs, companies and organizations. Some companies hire teams and invest in powerful artificial intelligence algorithms to police and remove illegal online content. Despite restrictions, all websites except TikTok can still be accessible to Chinese users by using VPNs, which are currently heavily restricted but not banned due to them often being used for business purposes.
