The Counter Extremism Project (CEP) reports weekly on the methods used by extremists to exploit the Internet and social media platforms to recruit followers and incite violence. This week, CEP located a profile on the gaming distribution service and social network Steam that either belongs to Christchurch shooter Brenton Tarrant, or is a replica of his account. Additionally, a pro-ISIS affiliate group released a new online magazine for the India region calling for violence. Also, five alleged Atomwaffen Division (AWD) members were arrested, resulting in far-right Telegram groups criticizing the formation of groups like AWD due to the risk of being apprehended for taking illegal actions. Four white supremacist Telegram channels were removed, including one notorious for dispersing accelerationist content inciting violence, however all four channels were either reinstated or were replaced. CEP also located German AWD propaganda on the Imgur and ibb.co platforms. Finally, an anti-Semitic Telegram account opened profiles on Twitter, Facebook, Gab and Parler.
