Naver said on April 23 it will automatically disable the comments service on news stories when malicious comments exceed a set threshold.

An AI-based detection system called Cleanbot will operate across all sections, including politics and elections, to detect malicious comments. If the threshold is exceeded, a notice reading, "Cleanbot has detected many malicious comments, so the comments service is not provided," will appear along with a Green Internet campaign banner.

Cleanbot, introduced in 2019, detects profanities, sexually explicit expressions, violent expressions, hate, disparagement and discriminatory expressions. Naver plans to upgrade the AI Cleanbot model later this month.

Naver leader Su-hyang Kim (김수향) said, "We are working to make it a place for communication through not providing comments at the bottom of articles in the politics and elections sections since last month and through advancing Cleanbot." She added, "We will continue to develop the service so it can respond to rapidly changing expressions in malicious comments."

Naver also introduced condolence comments in February to prevent secondary harm in articles related to accidents, disasters and obituaries.

So far, 23 media outlets have participated. Users can register the phrase, "May the deceased rest in peace," by clicking a button. As of this month, the ratio of comments to views on the story with the most condolence comments was about 6 times higher than other stories at the same media outlet.
