Online Grooming Statistics

A 2.5x jump in CSEA reports tied to online grooming content shows how quickly grooming tactics are shifting, while 90% of grooming-related activity in one research sample happens through direct messages rather than public posts. You will see what that means for triage, moderation accuracy, and real prevention gaps, including 6.2% of users escalating contact after encountering grooming-like messages and the practical safeguards schools and platforms invest in.

Online grooming is still rising even as platforms add tools. In 2023, UK reporting received 1,800 reports of child sexual abuse involving children that included online grooming related material, and one regulator noted a 2.5x increase in online grooming linked CSEA reporting between 2020 and 2023. The most sobering pattern is how quickly grooming can shift into private messages and off platform contact, turning detection into a time critical challenge.
