According to CBS Radio's 'Kim Hyun Jung News Show' on October 20, a Twitter account selling idol stars' personal information has been found. The seller provides idol members' phone number, Kakao Talk ID, social media passwords, and even hidden camera footage of idol members in their dorms, on a date, or kissing their girlfriend. 

It's reported the seller installs hidden cameras or microphones in locations after finding out the idol's schedule ahead of time. The cost of the information depends on the idol's popularity. Phone numbers are usually sold for 7,000 KRW (6.18 USD). 

Employees and associates of entertainment agencies are the suspected sellers. Meanwhile, JTBC also recently reported that they found people selling idols' flight information to sasaeng fans. 

The illegal sale of idols' personal information is a growing issue. Many netizens are requesting a thorough investigation to put an end to the illegal sale and violation of privacy.
