Zombie followers and fake re-tweets

IN THE year 15AD, during the short-lived Xin dynasty, a rumour spread that a yellow dragon, a symbol of the emperor, had inauspiciously crashed into a temple in the mountains of central China and died. Ten thousand people rushed to the site. The emperor Wang Mang, aggrieved by such seditious gossip, ordered arrests and interrogations to quash the rumour, but never found the source. He was dethroned and killed eight years later, and Han-dynasty rule was restored.

The next ruler, Emperor Guangwu, took a different approach, studying rumours as a barometer of public sentiment, according to a recent book “Rumours in the Han Dynasty” by Lu Zongli, a historian. Guangwu's government compiled a “Rumours Report”, cataloguing people's complaints about local officials, and making assessments that were passed to the emperor. The early Eastern Han dynasty became known for officials who were less corrupt and more attuned to the people.
