A rogue AI uses social programming to manipulate a group who intend to use an ex-Soviet Asiatic republic to take the illegal proceeds of crime from bad guys and set up a money trail to allow for their prosecution by various government entities. Very interesting concepts regarding social networking and the use of AI’s to recognise and target spam and the use of the same networks to manipulate via social engineering the users of said networks into acceptable behaviour.
