South Korea had ID-based web for two decades, everything you say is recorded and tied to your identity, forever. Please do educate yourself about the state of the political speech in the Korean part of the web.
In 2012, South Korean judges found the following to be unconstitutional [0], e.g. based on the person who complained about not being allowed to comment anonymously on YouTube and other sites (since Korean YouTube and other sites needed them to identify their real identity first):
1. Act to Promote Use of Communications Network and to Protect Information (as amended by Act No. 9119 of 13 June 2008)
2. Article 29 and Article 30, Paragraph 1 of the Enforcement Decree of the said Act (as amended by the Presidential Decree No 21278 of 28 January 2009)
Also, the Korean "Real Name" requirement was "rolled back", as reported at [1], which describes that "Article 44-5 of the Act on Promotion of Information and Communications Network Utilization and Data Protection, etc. (the 'ICN Act') was enacted in 2007... It required large-scale portal sites with more than 100,000 visitors on average a day to record the real name identities of visitors posting comments, usually via the poster's resident registration number (RRN).".

South Korea was under the Park dictatorship for a big chunk of its history. Most of Europe was under dictatorship of one kind or another within living memory. Seems some people can't lose that mentality.
