The emergence of suicide-promoting groups and sites poses a critical public health concern; however, there is a notable lack of comprehensive research on these entities at a global level. Given that young people, particularly adolescents, constitute a significant portion of online platform users and that suicide rates are alarmingly high within this demographic, it is crucial to examine these intersections. Such understanding is essential for designing and implementing effective suicide prevention initiatives that can address the unique vulnerabilities of this population. This chapter investigates the types of suicide-promoting sites and groups, targeted demographics, and associated risk factors, along with the grooming strategies employed to engage users. Additionally, it highlights the psychosocial and cultural factors that contribute to these issues, as well as the legal protocols, ethical practices, and limitations surrounding them. Ultimately, the chapter advocates for enhanced prevention and intervention strategies to address the growing concerns associated with these entities.
