Holy crap! You see last year, in response to the suicide of actress Choi Jin-sil, the South Korean government thought that cracking down on netizens ("net-citizens") who left cruel comments about her that supposedly pushed her over the edge would prevent suicide. (Because of course mean comments are the LEADING cause of suicide--not mental health problems and health care accessibility, no...). They thought people would be less inclined to be net bullies if they have to sign their real name to their comments. So they passed a real-name verification law.
Anyhow... I seem to be able to get around it by setting my location to "Worldwide" instead of "South Korea"
So I bring you Princess, talking to the birds:
Perhaps she is trying to learn Korean, and got confused...
