KBS sued Jang Yong-jin, a reporter for Ajou Economics, who had been accused of sexually harassing KBS excitement by appearing on the YouTube channel 'Alileo' to the Seoul Metropolitan Police Agency.

Jang was controversial when he appeared in 'Alileo' and said that prosecutors liked KBS's reporter and wrote the investigation.

KBS also sued 14 reporters who left malicious comments or sent mail or text messages to KBS reporters for defamation and insults.
