Every day, a largely invisible workforce reviews the worst material the internet produces — child sexual abuse material, violence, exploitation and hate speech — so the rest of us don't have to. Peer-reviewed research is increasingly clear that this work carries a real psychological cost: repeated exposure to this content is associated with PTSD, depression, burnout and other trauma-related difficulties, with higher exposure linked to higher distress. Understanding internet content moderation trauma is the first step toward building safer, more accountable systems for the people who do this work.

This hub brings together four evidence-based policy briefs, each written for a different audience with a role to play in protecting content moderators' mental health and wellbeing. Together, they set out what needs to change — in regulation, in the workplace, in clinical care, and in public understanding — so that support for moderators moves from an afterthought to a shared responsibility.
