The fake commenters are being paid by the government

It’s hard to figure out exactly who is being paid to comment by the Chinese government and who is not. While accusations of membership in the 50 cent army are rife on social media, these accusations are at best unreliable and at worst downright misleading. However, KPR were able to take advantage of a major leak of information to figure out what is happening. A blogger released a trove of emails from the propaganda office of a mid-sized unit of China’s local government. These emails included a little over 40,000 unambiguous examples of 50 cent army comments. KPR were able to use these comments to draw conclusions about how fake commenting works. They were also able to train a specialized machine learning algorithm to hunt down and identify similar comments on Chinese social media so that they could get a broader understanding of the ecology of government-sponsored comments in China.

One initial result is surprising. Many people think of the 50 cent army as independent contractors who are paid a small amount of money for each comment they make. If KPR are right, then this is far from the mark. The commenters identified in the leak appear to be regular government employees. The sample of emails that King, Pan and Roberts analyze suggests that they work directly for the Communist Party or for different organs of the local government, and presumably are expected to write these comments as part of their official duties.

Nearly 450 million government comments go up every year

KPR use statistical techniques to figure out how many social media comments are generated by people paid by the government. The results are startling. Government employees generate about 448 million comments every year. A little over half of these comments are made on government sites, albeit pretending to be comments made by ordinary citizens. The rest are made on commercial sites, mixed into streams with family news, dog photos and the like. The result, as KPR describe it, is that a “large proportion of government web site comments, and about one of every 178 social media posts on commercial sites, are fabricated by the government.”

To be clear, these figures depend on a certain amount of extrapolation and educated guesswork, which KPR describe in the paper. Even so, their results are plausible. They asked a random sample of the people whom their techniques identified as paid to write for the government, whether they were doing this professionally. They also asked people whom they knew to be paid by the government, because they were identified thanks to the leak, whether or not they were paid professionals. More or less the same percentage of both groups — nearly 60 percent — effectively admitted that they were.

Fake commenters are not paid to stir up controversy

There are many popular rumors about what government-paid commenters do. Some — especially non-Chinese commentators — think they are paid to stir up hatred and resentment of foreign countries such as the United States. Others believe that they are paid to respond to criticism of the government with bogus argumentative talking points.

KPR’s evidence suggests that both of these are incorrect. Paid government commenters don’t seem to say many nasty things about foreigners. Nor, for that matter, do they engage in argument on the Internet. Instead, they praise and distract. They write posts that cheerlead for the government. They also try to distract the public, especially when they fear that there might be protests or other social and political activity that might be dangerous for the government. They don’t appear to care particularly when people complain about the government. Instead, they act when there is a real risk of popular upheaval. In KPR’s words:
