Naver to Block Comment Sections on News with Excessive Malicious Comments Detected by AI

Detecting Malicious Comments with AI
Daum News Restores Comment Section Last Month

Naver announced that starting from April 23, 2026, it will implement a policy to automatically disable the comment service on articles where malicious comments exceed a certain threshold. This policy applies to all articles, including those in the politics and election sections, and utilizes the AI-based detection system 'Cleanbot' to identify malicious comments.

According to this policy, if the number of malicious comments surpasses a certain standard, a notice stating "Cleanbot has detected a large number of malicious comments, so the comment service is not available" will be displayed along with the Green Internet Campaign banner.

Cleanbot, the AI-based malicious comment detection system that Naver first introduced in the industry in 2019, continues to be upgraded to detect not only profanity, sexually explicit, and violent language, but also hate speech, derogatory, and discriminatory expressions. Naver is also preparing an upgrade to the AI Cleanbot model by the end of this month.

Suhyang Kim, a leader at Naver, stated, "Last month, Naver stopped providing comments at the bottom of articles in the politics and election sections, and has been advancing Cleanbot to ensure the comment section remains a healthy space for communication. We will continue to listen to diverse opinions and further develop our service to respond to the rapidly changing expressions of malicious comments."

Since February, Naver has also been operating a 'memorial comment' feature for articles related to disasters, accidents, and obituaries, allowing users to express condolences and sympathy. So far, about 23 media outlets have utilized the memorial comment feature, and users can convey their condolences by simply clicking a button to post a comment such as "Rest in peace." As of last month, an analysis of the ratio of memorial comments to views for the articles with the most memorial comments showed that these articles received over six times more comments compared to other articles from the same media outlets.

Meanwhile, the portal site Daum also reopened its news service comment section at the end of last month. Since June 2023, Daum had replaced comments with 'Timetalk,' a real-time chat service where users could leave opinions on articles, but all content would automatically disappear after 24 hours. Through this update, Daum now allows comments to be sorted by most recommended, most replied, or most recent, and has introduced 'AI Pick,' which pins the most relevant and complete comments related to the article at the top.
