Documentation and analysis of online abuse targeting Collective Shout This report examines the sustained campaign of hostility, harassment and harm directed at Collective Shout during 2025-26 following its advocacy to remove video games depicting rape, incest, sexual torture and child sexual abuse material from the digital distribution platforms Steam and Itch.io.

This OHPI report examines changes to antisemitism across ten social platforms from the year before October 7 through to the second anniversary of the attack. It reflects a sharp rise in the months after October 7, a decline later in 2024, then a renewed rise in antisemitism during 2025. On four platforms the level of antisemitism is now higher than it was in the months immediately after October 7, and on three of them the current level is at an all time high.
We’re please to share the Online Hate Prevention Institute’s annual activity reports covering the period 1 July 2023 – 30 June 2024, and 1 July 2024 – 30 June 2025. We have combined these into a single report.
In November 2024, the Addas Synagogue in Melbourne was set alight. In July 2025 the entrance to the East Melbourne Synagogue was set alight. These attacks on places of worship are just part of the rise in antisemitism in Australia since October 7, 2023. This report examines some of the online responses to these attacks, highlighting discourse, largely built around conspiracy theories, that is dismissive of, or even supportive of, attacks targeting Australian Jews.
