Violent Online Networks

Includes a Live Web Event on 08/26/2026 at 3:00 PM (EDT)

This presentation focuses on the growing threat of online extremist networks and the unique challenges they present when identifying victims and conducting interviews. VON refers to decentralized online extremist networks that target vulnerable individuals, often minors, through social media platforms, gaming spaces, and encrypted messaging apps. These groups use manipulation, coercion, and psychological control to exploit victims. Tactics may include grooming, threats, humiliation, self-harm coercion, sexual exploitation, and the production of violent or degrading content. Unlike traditional organized groups, these channels operate through loosely connected online communities that encourage escalating harm, radicalization, and control over victims. Victims are often isolated, fearful, and manipulated into believing they cannot leave or report the abuse. An opportunity for Q&A will follow the live presentation.
