He co-authored Terrorgram's three major zine-format publications and co-ran its Telegram channels until his arrest on December 8, 2023. On March 27, 2026, Ontario Superior Court Justice Jane Kelly sentenced him to 20 years in Canadian federal prison (parole-eligible at 10 years) following his guilty plea to three terrorism charges, finding that his propaganda had directly inspired at least six attacks including the [October 2022 Bratislava shooting](/people/juraj-krajčík/) and a 2024 mosque stabbing in Turkey.[^1][^2] ### Background and AWD Connection Before co-founding Terrorgram, Althorpe had been active within Atomwaffen Division's propaganda infrastructure from approximately 2018, producing accelerationist content in that context. He also had documented involvement with Active Club Canada, the Canadian branch of the far-right physical fitness and organizing network founded by American white nationalist Robert Rundo. His pre-Terrorgram history placed him at the nexus of the post-AWD accelerationist diaspora that coalesced on Telegram following AWD's partial disruption by federal prosecutions and the deplatforming of platforms like [Iron March](/organizations/iron-march/). ### Terrorgram Publications Althorpe co-authored all three of Terrorgram's major publications as part of the collective's inner circle: *Militant Accelerationism: A Collective Handbook* (136 pp., June 2021), framing terrorism as "the language of the unheard" and providing ideological and tactical guidance for lone-wolf attacks. *Do It For The Gram: The Collected Writings of Terrorgram* (268 pp., December 2021), maintaining and extending the first publication's operational argument. *The Hard Reset: A Terrorgram Production* (261 pp., July 2022), the network's most operationally specific work, with detailed instructions for attacks and critical infrastructure sabotage. These publications became the Terrorgram Collective's most widely cited and distributed output, circulating through the broader accelerationist Telegram ecosystem and reaching individuals who had no prior direct AWD or Terrorgram connection.[^3] ### Arrest and Prosecution Althorpe was arrested on December 8, 2023 in Canada and charged with three terrorism offenses under the Criminal Code of Canada: facilitating terrorist activity, instructing others to carry out terrorist activity, and committing an indictable offense for a terrorist group. He pleaded guilty to all three charges. On March 27, 2026, Ontario Superior Court Justice Jane Kelly sentenced Althorpe to 20 years in Canadian federal prison, with parole eligibility at 10 years. Justice Kelly found that Althorpe's publications had directly inspired at least six attacks, including the October 2022 Bratislava LGBTQ+ bar shooting by [Juraj Krajčík](/people/juraj-krajčík/) and the August 2024 [Eskisehir mosque stabbing](/people/arda-küçükyetim/) in Turkey. The Public Prosecution Service of Canada described the sentence as reflecting the severity of publishing propaganda that served as an operational guide for mass violence.[^1][^2] The sentence made Althorpe one of the most heavily sentenced Terrorgram figures in any jurisdiction, behind only [Dallas Humber](/people/dallas-humber/)'s 30-year U.S. federal sentence.
