A police investigating the 'Doctor's' telegram chat room where sexual exploitation was distributed is accelerating the pursuit of paid members who have dealt with operator Jo Joo-bin.

While the police figured out the cryptocurrency wallets and transactions that Joe had been using, he paid money to Joe and hired over 10 paid members who participated in the chat room to begin a full-scale investigation.

They were suspected of possessing sexual exploitation against children, and the police were found to be in the first place.

So far, there are many people in their thirties who have been targeted by the police, and there are no minors.

The police have secured more than 15,000 nicknames of members who have already joined the chat room.

If the police go through the process of comparing member information and cryptocurrency transaction history, the number of people to investigate is expected to increase.
