Scenarios

An Internet site in South Korea protests the current government. Is the content of this site protected by the South Korean constitution?

Why or why not?

A disgruntled ex-employee of a company makes a site that posts false negative information about his/her former company, should this site be allowed to stay up?

A person in South Korea signs up for the Internet through a local service provider and is asked to give a whole lot on information including information on their ideological background, birthplace, political identity and sex life. Should this be allowed?

One day state prosecutors walked into a person's home and arrested someone without a warrant for writing obscene material. Should this happen in South Korea? Discuss both morally and legally.
