"Since January 2021, Tech Against Terrorism has identifi ed 198 websites that we assess to be operated by terrorist actors, or by violent extremists that pose a credible and urgent threat to society. 79 of these sites relate to violent Sunni Islamist actors, 18 to violent Shia Islamist actors and 101 linked to the violent far-right. In 2021 we facilitated the removal of 16 of these sites that linked to accelerationist neo-Nazi actors, the Taliban and the Islamic State. From a representative sample of 33 terrorist- and violent extremist-operated websites, we found that: 91% displayed audio/visual progaganda; 73% had an archive of historic content; 57% included a communication feature. The total average monthly visits to these 33 sites is 1.54 million." (Executive summary)
