Over the past few years, authorities in China have waged a dramatic war on rumors, "fake news" and other spurious information online. Critics warn that the campaign is a tightening of the screws that will directly affect free speech in the country.

However, it appears that the campaign may be more targeted at actual rumors -- as opposed to essentially anti-government sentiment -- than you might expect. A report released Monday by the University of Toronto's Citizen Lab investigated what messages had been deleted from WeChat, the leading messaging app in the country.

The group monitored 36,000 posts on WeChat and found that the censorship was unusual in that while posts relating to political news were often targeted, so were tabloid rumors and other clearly fake news. The study's author, Jason Q. Ng, notes that some of these rumors seem "silly and harmless relative to other kinds of sensitive content."

The report gives examples of some of the posts that were censored, so you can see for yourself what the Chinese government was apparently so worried about. It includes a broad range of information, such as political speculation, tabloid fodder and conspiracy theories.

In his report, Ng notes that even the stupidest rumors may have a political component to them, because they are often spread by Chinese readers dissatisfied or distrustful of the official narratives. "Online rumors have much greater power than the mere contents of the message," he writes.

WeChat, which is owned by the Chinese tech giant Tencent, is well known for quickly spreading rumors among Chinese netizens. “Why is the level of trust in information on WeChat so high? Because information spread on WeChat comes from family and friends, and not strangers,” Kuang Wenbo, a professor at Renmin University’s School of Journalism and Communication, said a news briefing last month, according to the Wall Street Journal.

The report also details how WeChat has a list of sensitive terms that cannot be published and, therefore, do not feature in censored or uncensored posts. These words often related to touchy political subjects, such as  六四 (June 4) and 太子党 (princeling).
