TikTok—Multiple studies found TikTok algorithmically suppresses content critical of China including Uyghur, Tibet, and Tiananmen topics
Research by Rutgers University Network Contagion Research Institute (2023-2024) found TikTok's algorithm systematically suppresses content critical of China's human rights record. Searching for 'Uyghur' on TikTok returned only 2.5% anti-CCP content compared to 50% on Instagram and 54% on YouTube. For Tibet searches, 61-93% of results were pro-China or irrelevant. Leaked internal moderation guidelines (2019-2020) had explicitly directed moderators to censor content about Tiananmen Square, Tibetan independence, and Xinjiang. CEO Shou Zi Chew denied censorship during 2023 Congressional testimony, contradicting a UK parliamentary admission by TikTok executive Elizabeth Kanter that such policies had existed.

Rutgers NCRI study found only 2.5% of TikTok Uyghur search results were critical of China vs 50% on Instagram
The Rutgers University Network Contagion Research Institute published research in August 2024 finding TikTok's search algorithm systematically downranked content critical of China. Searching for 'Uyghur' returned only 2.5% anti-CCP content on TikTok compared to 50% on Instagram and 54% on YouTube. For Tibet-related searches, 61-93% of results were pro-China or irrelevant. Heavy TikTok users (3+ hours daily) showed a 49% increase in positivity toward China's human rights record compared to non-users.
Leaked TikTok internal guidelines directed moderators to censor Tiananmen Square, Tibet, and Xinjiang content
The Guardian obtained leaked internal TikTok moderation documents in September 2019 showing moderators were instructed to filter content related to Tiananmen Square, Tibetan independence, and issues sensitive to the Chinese government. The Intercept obtained further documents in March 2020 showing moderators were directed to censor political speech in livestreams, including banning those who 'harmed national honor.'
