The "Momo Challenge" was an internet hoax and urban legend that was rumoured to spread through social media and other outlets as a creepypasta. It was reported that children and adolescents were being harassed by a user named Momo to perform a series of dangerous tasks including violent attacks, self-harm, harming others, and suicide, mirroring the earlier Blue Whale Challenge. Despite claims that the phenomenon had reached worldwide proportions in July 2018, the number of actual complaints were relatively small and many law enforcement agencies have not been able to confirm that anyone was harmed as a direct result of it. Moreover, the Momo Challenge sparked global panic and prompted urgent warnings from authorities and child safety advocates. Reports of children encountering Momo's disturbing messages circulated widely, causing heightened fears among parents and caregivers.
