The "Momo Challenge" was a hoax and an internet urban legend that was rumoured to spread through social media and other outlets. 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. Despite claims that the phenomenon had reached worldwide proportions in July 2018, the number of actual complaints was relatively small and many law enforcement agencies have not been able to confirm that anyone was harmed as a direct result of it.Discussions among YouTube commentators about a new internet phenomenon promoting self-harm similar to the Blue Whale Challenge surfaced in July 2018, followed in August by news items reporting allegations that cases of self-harm by children in South America and India had been prompted by WhatsApp messages.[1] Reports were based on stories of teenagers being targeted by people presenting themselves as a character named Momo, trying to persuade people to contact them through their cell phone. As with other Internet hoaxes presented as challenges such as "Blue Whale", players are then instructed to perform a succession of tasks; refusal to do so is met with threats and gory pictures.A representation of the Momo character appeared in the popular game Minecraft in the form of in-game skins and an unofficial mod created by the game's users. A police officer in Ohio was concerned to see Momo in his son's copy of the game, worried about the possibility that the mod could lead to participation in the Momo Challenge. After news reports started to outline the link between the Minecraft mod and the Momo Challenge, Microsoft announced it was taking measures to "restrict access to the mod" in question
