North Korea build TROLL ARMY to tear down S Korean surfers

North Korea has tasked 200 agents with the job of posting negative comments online, often using stolen online identities, in a bid to undermine the morale of their neighbours in the South.

The brigade of NORK trolls is part of a brigade of 3,000 cyber warriors and hackers that make up the Reconnaissance General Bureau information warfare force, according to the Police Policy Institute.
