After the victims are enticed to contact a Momo account through social media network WhatsApp, they receive graphic threats and are instructed to perform a series of dangerous tasks. The scheme may include hacking the victim's phone. Despite claims that the phenomenon is reaching worldwide proportions,the number of actual complaints is quite small and no police force has confirmed anyone was actually harmed.The "Momo Challenge" relies on threats to get the victims to perform tasks. Targeting teenagers, "Momo" relies on Whatsapp messages to convince potential victims to use their mobile phone to contact one of several "Momo account" phone numbers. Whoever has set up the account then repeatedly threatens the victim to make personal information public (doxing), or inflict harm on family members, unless a succession of tasks is performed. Some victims are threatened with supernatural harm such as magical curses. The threats and subsequent communications are often accompanied by disturbing, scary or gory pictures.Its spread are stoking fears that this could be the next Blue Whale. WhatsApp is encouraging its users to block phone numbers related to the Momo Challenge and to report them to the company. Picture of "Momo" To represent "Momo", the accounts use the picture of a woman/bird sculpture produced by special effects firm Link Factory. The firm denies any involvement with the current unpleasantness. The pictures have been posted online in 2016, when the sculpture was publicly exhibited. With its bulging eyes and huge mouth, images of the sculpture can be quite scary. A close-up of the face gives the impression of a mask, or a woman with strangely distorted features. Early news reports stating the image was of a sculpture of Japanese artist Midori Hayashi turned out to be incorrect. Hayashi indicated that was not her piece and Internet users identified the correct source.
