A policy, so called “a real name internet system” has brought an extraordinarily controversial issue and generated a sharp division of opinions those who approve and disapprove the system. After creating such an antagonistic relationship between two groups of people for more than five years from 2007 to 2012, a real name internet system had been abolished by the ruling of the Constitutional Court of South Korea (hereafter “Korea”) in August 2012. Simply put, the Constitutional Court said that the system does not seem to have been beneficial to the public and the number of illegal or malicious postings online has not decreased despite the enforcement of the system.
