This chapter critiques prohibitionist approaches to online safety and youth sexual image sharing, arguing that attempts to eradicate crime by policing victims perpetuates harm rather than preventing it. Drawing parallels with drug policy’s “ratchet effect”, it shows how moral panic and political rhetoric lead to increasingly restrictive legislation. Using examples from the Headstart project, the chapter presents a harm reduction model grounded in children’s rights. It outlines how prohibitive messaging violates rights to expression, privacy, and participation. While harm reduction emphasises non-judgmental dialogue, informed consent, and empowerment, and therefore better protects and educates young people. The chapter uses the adapted principles of harm reduction outlined in Chap. 2 in the development of training for professionals. This training reveals gaps in knowledge and confidence across the children’s workforce. It concludes by recommending wide implementation of digital safeguarding training using the harm reduction approach to replace fear-based prohibition with rights-based resilience and genuine protection for young people.
