Muhammad Zain Ul Abideen Rasheed, a sex predator posing as a 15 year old famous teenage YouTube star who blackmailed hundreds of girls around the world has been jailed for 17 years in Australia.

Two thirds of his victims were under the age of 16 from countries including the US, Japan and France. He pleaded guilty before the Perth court to 119 charges relating to 286 people.

Pretending to be an internet star, the predator would start up a conversation with his victims before involving them in talks on sexual fantasies.

He would later force them into extreme abuse by threatening to send explicit messages and images of them to their loved ones.

Some of the degrading acts at times included family pets and other children in their home.

Rasheed is also said to have been involved in misogynistic ‘incel’ communities where in some occasions would invite other people to watch the distressing acts on livestream.

He continued with the blackmail despite knowing the fear and distress his victims were going through.

“The callous disregard this man had for his victims around the world and their distress, humiliation and fear make it one of the most horrific sextortion cases prosecuted in Australia,” said Australian Federal Police Assistant Commissioner David McLean.

He is already serving a 5-year prison term for sexually abusing a 14 year old into occasions in his car at Perth Perk. Rasheed will be eligible to apply for parole in August 2033.

Australian authorities say it is “one of the worst sextortion cases” in history.
