South Korea faces deepfake porn 'emergency'

South Korea has a dark history of digital sex crimes. In 2019 it emerged that men were using a Telegram chatroom to blackmail dozens of young women into performing sexual acts, in a scandal known as nth-room. The group's ring-leader, Cho Ju-bin, was sentenced to 42 years in jail. Online deepfake sex crimes have surged, according to South Korean police. A total of 297 cases were reported in the first seven months of this year, up from 180 in the whole of last year and 160 in 2021.
