But I doubt it is for the curse words or the poor grammar.
It could be the numerous North Korean themed pictures, posts and youtube clips.
But it's not because of my views on freedom of expression.
It all started on Monday...
You see, under the South Korean National Security Act (국가 보안법) Posting NK-Friendly stuff will land your ass in jail (or not):
Relaying and posting material sympathetic to North Korea and its leader Kim Jong-il on the Internet is a clear violation of the National Security Law, a court ruled Monday.
The Seoul Central District Court sentenced a 40-year old man, identified only by his surname Lee, to two years in jail, suspended for three years, finding him guilty of disseminating documents and songs praising the communist state and its activities.
Songs!
Oh oh!
The K-Times continues:
It was the first time for an individual to be found guilty of violating the National Security Law for simply uploading a hyperlink on the Internet, which leads those clicking it to documents, songs and other materials lauding North Korea.
In March, the prosecution took Lee into custody and indicted him on charges of posting and disseminating a total of 433 pieces sympathetic to the North. He was accused of uploading hyperlinks on a community cafe on Daum, one of the country’s largest portals.
Interesting that this is the first time an individual has been knicked - but not surprising, my meagre attempts at satire here at The Chosun Bimbo pale into nothingness in comparison to the nearly 500 links etc that Mr Lee had up on Daum.
And as long as everyone remembers that anything I post about North Korea is usually a (poor) attempt at satire or Irony and that I don't, under any circumstances, agree with, like, or otherwise support the dictatorial, oppressive, inhumane actions of the tyrant madman Kim Jong Il and his cronies, I should be fine.
After all, The National Security Law prevents the distribution of material lauding the North or unauthorized activities sympathetic to the Stalinist regime. Neither of which I am doing.
And then along came Tuesday...
From Kushibo:
I will say, though, I dread the eventual message I get that reads, "Kushibo, North Korea is now following you on Twitter." That is, if it isn't happening already.

That's right, after many an imitator, The DPRK has an official North Korean Twitter feed though Twitter hasn't verified it yet! By the way - the above image is all you will see of the feed as the page is now blocked in South Korea. (Thanks again to Kushibo for the pic) If you were able to follow @Uriminzok from SK before the banning its posts will still show up on your Twitter Home page or in any of the clients you may use.
But on the back of Mr Lee's case a couple of people were starting to freak out by Tuesday afternoon, given the huge popularity of Twitter in Korea (South that is).
From Tuesday's K-Times:
Twitter users are increasingly expressing concerns over possible violation of laws for subscribing to a North Korean micro-blogging site, which opened last Thursday under the name “uriminzok,” or “our people.”
Such fears are attributed to the National Security Law which states any person who corresponds or communicates with an anti-government group is subject to a maximum jail term of 10 years, if they were aware that their act could threaten national security.
Under the inter-Korea Exchange and Cooperation Act, those contacting North Koreans without first reporting to the Unification Minister can be fined up to 3 million won ($2,500).
“The North Korean Twitter site is now the talk of the town,” a college student with the screen name Leehuna tweeted.
“I wonder following the site is a breach of the National Security Law?”
Well yes, in addition to the Inter-Korea Exchange and Cooperation Act, which I hadn't heard of until this week.
later in the article is this beauty:
Seoul has banned 65 websites considered sympathetic to Pyongyang since 2004 by blocking IP addresses, but the matter seems much more complicated with Twitter.
Well apparently not....
And elsewhere My dear friends the Korea Communications Commission (remember them - they also deal with the phones) seems to be reading Roboseyo, having apparently discovered The DPRK's (pretty lame) Official YouTube channel:
“Now, it appears that it will need to have long discussions with Twitter and YouTube on technical matters and legal terms on blocking South Koreans from accessing certain sites created by North Koreans.”
In July, Pyongyang created its own channel on YouTube, uploading video footage that praises its leader Kim Jong-il and defends itself against allegations over the sinking of the Cheonan warship in March.
The big concern though, is not that North Korea is about to turn Southern Liberal Democracy on it's head, but rather by banning it's Twitter feed, South Korea is killing free speech.
In addition I challenge you to find a A South Korean inclined to use Twitter who would actually take @Urimminzok's insane ramblings seriously. For example here is Twitter user @SSSSSunny:
방송통신심의위 심의를 거쳐 적법하게 차단됐다는 북측 것으로 추정되는 계정@uriminzok가 정말 자유민주주의 기본 질서를 해칠 만큼 위험하던가요? 공권력은 필요하다면 사회적 합의를 통해 더한 조치를 취할 수도 있겠지만 늘 '자의적'이어서 문제입니다
Roughly translated it says deliberations are needed before arbitrarily blocking North Korea's twitter feed.
And to prove the near impossibility of North Korea corrupting the Twitterers of The SOuth - How could anyone belive this:
uriminzok 최근 조선에서 효능높은 암왁찐 개발 암재발, 전이예방약(암왁찐)이 환자치료에서 놀라운 효과를 내고있어 의학계의 이목을 집중 http://tinyurl.com/36cuwb8
Yes apparently North Korea has cured Cancer. And finally rlaalswo8 reminds us that all this twittering is just playing into the North's hands - ater all it's hardly for domestic consumption. WHatis the penetration of PCs in homes in North Korea?
김민재(@rlaalswo8)님이 공유한 이야기: "zkfldiwls: RT @anyfree21: @uriminzok 북조선 인민들은 여름에 어떻게 사는지 궁금합네다~ 아 그리고 북조선인민들의 컴퓨터 보급률은 어떻습네까 ?"
I suppose we can chalk this one up to another attempt by the current puppet regime Lee Myung Bak administration to curb expression on the Internet.
