Until recently, South Korea was the first and only country that legally required internet users to register their real names and national identification numbers with internet portals before commenting or contributing content online. The Constitutional Court held this controversial Real Name Verification System unconstitutional, liberating anonymous online expression, and perhaps more importantly, restraining the government’s ability to potentially abuse access to this information and snoop on internet users’ online activity.

With a population that exceeds 10 million living in an area half the size of New York City, Seoul is one of the most densely populated cities. Furthermore, surrounded by sea and North Korea, the geographical constraints exacerbate the sense of crowdedness. The open and boundless internet allows Koreans to retreat from this confinement, possibly explaining why South Korea is one of the most wired countries in the world with many citizens spending most of their time on the cyberspace. According to research, PC Tablet users in Korea on average spend 11.75 hours online everyday, and the number would probably be even greater if they could eat and sleep on the internet.

The internet, thus, has clearly become an important part of Korean society. Due to the extensive, affordable, and non-discriminatory access it provides to Korean citizens, the internet arguably has created the most vibrant “marketplace for ideas” and the important forum for democratic and political participation in Korean history. However, it has also given rise to a wide array of social issues. While much of the commentary online is undoubtedly products of thoughtful reflection and rational deliberation, unfortunately, the South Korean web is also full of hostility, gossip, “disinformation, rumors, and garbage.” Lyrissa Barnett Lidsky, Silencing John Doe: Defamation & Discourse in Cyberspace, 49 Duke L.J. 855, 893 (2000).

In a 2011 South Korean survey, 54.4% of the respondents stated that they have been victims of online hostility. Online insults were becoming a trend in South Korea until 2008 when Choi Jin-sil, a famous Korean actress nicknamed “the Nation’s Actress” committed suicide after a storm of careless rumors and insulting comments quickly transformed what really should have been Choi’s personal and private issues into a national phenomenon. Following this incident, public support for regulating online expression dramatically increased, facilitating government efforts to implement the Real Name Verification System aimed at combating online anonymity.

Under the Real Name Verification System, “internet portals with more than 100,000 users per day [were required] to confirm the identities of content contributors by requiring them to disclose their Korean national identification numbers.” The government’s stated purpose of the law was to suppress online defamation and to make it easier to trace offenders. The Constitutional Court recognized this as a valid purpose, but found the law unconstitutional because it was not narrowly tailored to accomplish this goal, and had a significant chilling effect on legitimate online speech.

Indeed, it seems possible that the law is not very effective at curbing the kind of undesirable hostile comments, but does have a strong chilling effect on legitimate speech. Since most derogatory comments online are made between people who do not know each other anyways and only a minute fraction of the victims would be inclined to pursue litigation due to relatively high costs, revealing true identities of online commenters does not seem to be a very strong deterrent against online hostility. Indeed, statistics demonstrate that there was only a slight drop in the rate of malign internet posts (from 15.8% to 13.9%). In contrast, laws requiring users to reveal their identities to the government could discourage many users from critiquing government abuse, making politically controversial statements, and expressing various other legitimate ideas or concerns.

Thus, the Real Name Verification of Internet News Sites law, which requires online users to register their real name and national identification number with internet news sites in order to post messages “expressing support for or opposition to political parties or candidates . . . during the election campaign period,” seems excessively broad. While the law does serve a valid purpose of preventing small groups from “distorting public opinion . . . [with] malicious propaganda and false facts . . . during the short election campaign period,” making it difficult to rectify the distorted information in time, it also chills legitimate exchange of important political communication. In Buckley v. American Constitutional Law Foundation, Inc., Justice Ginsburg stated that constitutional protection "is at its zenith" for political speech, indicating that political expression is fundamental to democratic freedom. The Real Name Verification of Internet News Sites seems to be an excessive restraint against political speech.

South Korea can use its existing cyber defamation law, which is widely supported by the Korean public, to restrain online hostility. By repealing laws that chill anonymous speech and maintaining the defamation laws, South Korea can promote a healthier online environment where netizens can say what they mean, but without saying it mean.
