The Lucy Faithfull Foundation has published an impact report on Project Intercept, a global online prevention programme. Working in partnership with technology companies, the project delivers warning messages to individuals who are searching for, viewing or sharing child sexual abuse material, or engaging in sexual conversations with children online. These warnings aim to disrupt harmful behaviour, make the consequences clear and offer a route to help. The report covers how the messages work to disrupt and divert offending, how they encourage help-seeking behaviour, and the impact of Intercept on technology companies.
