Thailand's internet censorship is governed by the Computer Crime Act (CCA) of 2007 (amended 2017), which gives authorities broad powers to block websites, compel removal of content, and prosecute internet users. The Ministry of Digital Economy and Society (MDES) administers content blocking, while the Technology Crime Suppression Division (TCSD) investigates online offenses. Over 100,000 URLs have been blocked in Thailand.
The primary driver of censorship is Thailand's lese-majeste law. Any content perceived as disrespectful to the King, Queen, or royal family is blocked and can result in criminal prosecution. Sentences are severe - a woman was sentenced to 43 years in prison in 2021 for social media posts (later reduced on appeal). The law's vague wording creates a chilling effect where self-censorship is pervasive.
Beyond lese-majeste, the government blocks gambling sites, pornography, content critical of the military, and political content during sensitive periods. During the 2020-2021 pro-democracy protests, the government threatened to shut down Telegram and blocked several activist websites. Thailand has also been documented using Pegasus spyware against pro-democracy activists and human rights lawyers.
