The police have been tracking paid members based on their cryptocurrency remittance history, but the investigation of free members who downloaded sexual exploits without paying admission fees is also in earnest.



It was confirmed as a result of SBS interview that the National Police Agency has ordered the identification of 280 free members to be registered at each local police office.



Due to the lack of cooperation from the Telegram headquarters, it was difficult to track free members without remittances, but the police found a breakthrough when Jo Joo-bin gave free members the name of a specific victim in December of last year and ordered them to climb the rankings of real-time search terms.



A court warrant was issued to obtain a list of people who searched for a specific person's name in a specific time period on the portal, and compared and contrasted them with the free chat room participants found on Jo Joo-bin's mobile phone.
