标题： Troll Farms

摘要： 政治代理人常常通过网络水军——传播模仿真实信息的组织——来影响选举。 我们研究了一个面对多样化选民群体的网络水军的行为，这些选民部分了解情况，网络水军通过向每类选民发送特定的信息分布来实现期望的政治结果。 我们表明，当选民原本信息充足时，这种策略更为有效，例如当媒体质量较高时。 同时，极化程度的增加以及偏离贝叶斯理性的情况可能会减少网络水军的负面影响，并恢复选举结果的效率。 显示英文摘要

摘要： Political agents often aim to influence elections through troll farms -- organisations that disseminate messages emulating genuine information. We study the behaviour of a troll farm that faces a heterogeneous electorate of partially informed voters, and aims to achieve a desired political outcome by targeting each type of voter with a specific distribution of messages. We show that such tactics are more effective when voters are otherwise well-informed, for example, when the media is of high quality. At the same time, increased polarisation, as well as deviations from Bayesian rationality, can reduce the negative effect of troll farms and restore efficiency of electoral outcomes.
