A prime mover behind the Shirion Collective, a conspiracy-minded, pro-Israel disinformation network seeking to shape public opinion about the Gaza conflict in the US, Australia and the UK, is a tech entrepreneur named Daniel Linden living in Florida who co-wrote a guidebook for OnlyFans users, the Guardian can reveal.

Shirion has harassed pro-Palestinian activists, including many Jews, offered bounties for the identity of pro-Palestinian protesters, spread conspiracy narratives centered on figures like George Soros, and boasted of an AI-surveillance platform but offered few concrete details of how the technology functions.

The Guardian investigation used public records and open source materials to corroborate information originally provided by the White Rose Society, an Australian anti-fascist research collective.
