The Counter Extremism Project (CEP) reports weekly on the methods used by extremists and terrorist groups on the Internet to spread propaganda and incite violence. Last week, CEP researchers located 10 TikTok accounts that had either posted video footage from the 2019 Christchurch terrorist attack or glorified the shooter and an additional 11 TikTok accounts that promoted white supremacist groups or mass shooters, including the May 2022 Buffalo attacker.
