Mnet vote manipulation investigation

The South Korean television channel Mnet has been accused of electoral fraud in several of its reality competition series. Among them are the Produce 101 series and Idol School, which were intended to create K-pop groups with members selected by audience vote. In July 2019, during the final episode of the Produce 101 series' fourth season, Produce X 101, several viewers suspected that the total votes were manipulated after noticing numerical patterns. On August 1, 2019, 272 viewers filed a lawsuit against Mnet, as their on-site text voting service charged ₩100 per vote, prompting an investigation led by the Seoul Metropolitan Police.
