South Korea's new law targeting false information online is now in force, allowing courts to award punitive damages up to five times proven losses against news outlets and large social media accounts — including YouTube creators — that spread false or manipulated content. Platforms with over a million daily users must remove flagged content upon reports, with fines up to 1 billion won for repeat offenders. Critics, including the Journalists Association of Korea and the US State Department, warn the law could chill press freedom and turn platforms into censors, since platforms — not courts — make the initial call on what counts as false. The law was passed following a political crisis involving YouTube election-fraud claims, and its enforcement raises broader questions about who gets to define misinformation, especially as generative AI accelerates the spread of fabricated content.
