South Korean Supreme Court Upholds Life Sentence for Leader of Largest Online Sex Crime Ring

The Supreme Court of South Korea on Thursday upheld a life sentence for Kim Nok-wan, the leader of a Telegram based sexual exploitation network known as The Vigilantes. Kim, 34, was found guilty of exploiting 261 people, including minors, making this the largest domestic sex crime case recorded in the country. The court also ratified orders for Kim to wear an electronic monitoring device for 30 years, a prohibition on working at institutions serving children and adolescents, and the public disclosure of his personal information for 10 years.

Operating from August 2020 until January 2025, Kim used the alias Pastor and led a group that produced and distributed over 2,000 sexually exploitative images and videos. The group targeted individuals who posted revealing images on social media or sought paid dates, as well as men attempting to access pornography. Members blackmailed victims into providing nude photos or complying with other demands, and some victims were summoned and sexually assaulted in person. The scale of the operation exceeds that of previous major rings, such as the Baksabang case, which involved 73 victims.

While the court upheld the life sentence for Kim, it acquitted him and two accomplices of charges related to organizing or participating in a criminal group, citing insufficient evidence of a shared criminal association. The two accomplices had their sentences upheld: one received an indeterminate juvenile sentence of 18 months to two years, and the other received two and a half years in prison. The court described Kim's crimes as inhumane and noted that he showed no respect for human dignity.
