South Korean government ruled that the law that requires the use of real names online is unconstitutional.
Introduced five years ago to eliminate false rumours and cyber bullying, the law has been endlessly contended by free speech advocates and internet users alike. Among many criticisms, researchers point out that the law severely diminished user involvement in Internet communities.
Many websites flat out denied following this rule. Popular sites opted for social log-ins through Twitter, Facebook, and Me2Day instead of real name log-ins, and some international sites disabled certain functions for Korean users in order to circumvent the law. The best example is YouTube, who simply disabled commenting for Korean users in 2009 when it was asked by the government to display users' real names.
The Constitutional Court in South Korea decided that the law did not accomplish its intended goals, and only hurt freedom of speech, freedom to publish, and equality rights. This law is essentially dead. Good on ya, South Korea! Better late than never.
