Solution summary

Method
3DES-ECB, key MD5(name+title)
Result
39.06207,125.659641 ~ 201210141420-6 ~ 7T ~
Explanation
Hand-typed message (CRLF) sent through the bot's live MD5(name+title) encryption between draws 12 and 13 of run 335,015, with no draw used. The point is a pick 3.1 m from the centre of an unnamed 500 m2 building in Ryongsan-dong, Mangyongdae, Pyongyang. Same place/time/code layout as 114med and 1iwqql; the time (2 days ahead, -6 = UTC-6?) matches no bot or public event. 7T is unexplained
