In the democratic South, 100,000 sites -- both from in and outside South Korea -- are blocked or deleted a year, according to this year’s Korea Internet Transparency Report. In March 2016, North Korea Tech, a San Francisco-based news website on tech infrastructure in the secretive regime, was blocked in South Korea on grounds of spreading pro-North information. He launched North Korea Tech that same year to report spillover research he couldn’t cover at his day job. His website tracks content from the Korean Central News Agency, the Naenara web portal and North Korean media websites -- which are blocked in South Korea -- along with lists of North Korean radio frequencies that change every few months. For example, South Korea claimed one website article reported that North Korea was testing satellites, but in reality the story was about a failed satellite that strayed from its orbit.
