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 found numerous posts on Telegram, Twitter/X, and YouTube commemorating the second anniversary of the 2022 Buffalo terror attack, including sharing the attacker’s manifesto and violent footage, with some accounts explicitly advocating for further acts of white supremacist terrorism. CEP also located 12 TikTok accounts promoting the Buffalo attack and the Christchurch massacre, including content glorifying the attackers. These accounts were reported to the platforms or relevant authorities, but almost 75% remained online as of May 20.
