People are naturally conform _themselves_ to social expectations. You don't need to enforce anything. If you alter their perception of those expectations you can manipulate them into taking actions under false pretenses. It's a abstract form of lying. It's astroturfing at a "hyperscale."

The problem is this only seems to work best when the technique is used sparingly and the messages are delivered through multiple media avenues simultaneously. I think there's very weak returns particularly when multiple actors use the techniques at the same time in opposition to each other and limited to social media. Once people perceive a social stale mate they either avoid the issue or use their personal experiences to make their decisions.
