For 4 years, Koreans enacted increasingly stiff real-name commenting laws, first for political websites in 2003, then for all websites receiving more than 300,000 viewers in 2007, and was finally tightened to 100,000 viewers a year later after online slander was cited in the suicide of a national figure. The policy, however, was ditched shortly after a Korean Communications Commission study found that it only decreased malicious comments by 0.9%. Korean sites were also inundated by hackers, presumably after valuable identities.
Further analysis by Carnegie Mellon’s Daegon Cho and Alessandro Acquisti, found that the policy actually increased the frequency of expletives in comments for some user demographics. While the policy reduced swearing and “anti-normative” behavior at the aggregate level by as much as 30%, individual users were not dismayed. “Light users”, who posted 1 or 2 comments, were most affected by the law, but “heavy” ones (11-16+ comments ) didn’t seem to mind.
