> By the 1970s, the Stasi had decided that methods of overt persecution which had been employed up to that time, such as arrest and torture, were too crude and obvious. It was realised that psychological harassment was far less likely to be recognised for what it was, so its victims, and their supporters, were less likely to be provoked into active resistance, given that they would often not be aware of the source of their problems, or even its exact nature. Zersetzung was designed to side-track and "switch off" perceived enemies so that they would lose the will to continue any "inappropriate" activities.

Data mining is extremely useful and a significant technological leap, but data manipulation on a massive scale is definitely something to marvel at.

Facebook is already impersonating your friends and family by showing fraudulent "likes" (but hiding them from their owners so as to prevent discovery), now imagine that the people you respond to on reddit and HN aren't actually people but instead they're trojan horses -- bots meant to influence society by manipulating it. MSM will no longer be the only domain that our elite overlords encroach upon.
