A wave of criminal activity in Japan has been blamed on social media. Yami Baito – meaning “dark part-time jobs” in Japanese – refers to job ads posted by criminal gangs on social media and encrypted messaging platforms including Telegram. Jobseekers are blackmailed or enticed with the promise of getting rich quick to commit a range of crimes from scamming elderly people to, at its most extreme, armed robbery. Japanese police have attempted to crack down on Yami Baito by taking down these ads and launching public awareness campaigns. But BBC Trending explores evidence that these recruiters are still operating online. We hear from someone who got sucked into Yami Baito, and a criminal mastermind in charge of recruitment.
