Cataloguing Internet Censorship

Note: this blog post is a republication of my recent contribution to China Outlook with permission. China Outlook is “an online, subscription-only newsletter that specialises in writing and research about China’s future. Based in Hong Kong, it is editorially independent.” 

The composition in this photo is a very visual allegory for the attitude of many citizens towards what the government wants them to believe. The photo was taken outside a disco club by the name of “Propaganda” at Wudaokou, Beijing, in 2005. This sleeper is most likely a migrant worker from the surrounding countryside. He was using his shoes as a pillow, the only comfort he could afford, while resting on the hard concrete stairs. Credit: the same as the author of this blog.
  
Just before 6 am on 26 June 2013, rioting broke out in the town of Lukqan Township in Xinjiang Uyghur Autonomous Region, in northwest China and home to millions of Uyghur Muslims. At least 24 people were killed by suspected Islamists, who set about them with swords and knives. 

About seven hours later the state-run Xinhua News Agency broke the news on its English news wire service, followed closely by numerous Chinese news portals that covered the story with a Chinese translation. 

A few hours later, Chinese speakers living in the United States first heard the news on the BBC and CNN, both of which quoted the original report from Xinhua. But when they began to look on Chinese websites, they could find hardly a trace of the story. The censors had been at work. 

For those living in China and China observers such censorship of important events is not unusual. China has never been far from the bottom of the Press Freedom Index published by Reporters without Borders and is presently in 173rd position, with just six countries worse . Foreign websites are routinely blocked and Chinese websites are under continual, close scrutiny. 

According to the Harvard Berkman Center for Internet and Society, China devotes “substantial technical, financial, and human resources” to develop the apparatus of censorship and has instituted “by far the most intricate filtering regime in the world.” Since censorship is a common practice in China, censored information has become an alternative perspective that we should not neglect when seeking to understand this country. 

Censorship is a crude tool at the best of times and often the material censored carries crucial information for people both inside and outside China – even if it is too inconvenient for the Chinese authorities. The outbreak of SARS in 2002-3, for instance, was censored from Chinese media for five months, presumably to avoid spoiling the harmonious atmosphere created for the 16th National Congress of the Communist Party. However, the decision was not without implications: it allowed the virus to travel irreversibly across continents until a worldwide epidemic emerged. 

So too with other subjects, which, like SARS, are not only inconvenient but also crucial; in fact, it hardly makes sense to devote huge resources in terms of human labour and computing power to monitor and eliminate subject matter that was merely trivial. 

At the same time, the authorities’ decision to censor information that is inconvenient, even if it is important, provides an opportunity to observe China from the standpoint of what it discards, rather than what it consumes. And that is precisely what a number of researchers outside China have now begun to do – namely, to examine and assess news stories that have been censored from the Chinese media. 

Of course, the analysis of deleted stories will never provide a full picture of media control. In many cases journalists familiar with a particular regimen will know not to write certain kinds of stories. This is a form of pre-censorship. The journalists in a newsroom may often be privy to certain information that they know it would be foolish to circulate. But with articles that have appeared and then just as rapidly have disappeared, there is a different situation. In these cases, the material has been published, but is subsequently judged to be unsuitable and is removed. 

But how to collect this censored information before it vaporizes? In recent years scholars and institutes have been trying to uncover information censored from news portals and social media in China. A common technique involves two steps: collect and check. First, information published online in China is collected using big data techniques and, in the second stage, is repeatedly and continuously checked for availability. Once a link appears broken, it is “red flagged” for suspicion. 

While it is possible for articles to be removed completely for editorial purposes, in practice this is rare. In such cases, as with corrections to, say the New York Times website, it is usually possible to identify the corrections, through the use of italics or some similar device. 

Even stronger evidence to rule out alternative explanations beyond censorship can be obtained by comparing deletions in a variety of news media to see if they cover similar topics. If so, then censorship is a strong possibility, because similar deletions reflect the systematic control of content, which in turn is a good indication of regulated behaviour.

One recent censorship study conducted jointly by Michigan State University and the City University of Hong Kong focused on NetEase and Sina, two major news portals in China. 

From November 2011 to October 2012, the researchers found on average that two articles were deleted from each website per day and that the deletions from the two websites followed similar patterns. In particular, domestic news had a significantly higher probability of being deleted compared to international news: twice as likely for NetEase, and six times for Sina. Beijing stories had twice the probability of deletion compared to news covering other places in China. Surprisingly, very few articles on Tibet appear to have been deleted, a fact that the researchers put down to pre-censorship. Compared to neutral stories, for NetEase, positive news had one third the probability of being deleted whereas negative news nearly four times, and for Sina, negative news had three times the probability of being deleted. 

From a list of 13 news topics, five were strongly associated with deletions: politics, business, foreign affairs, food and drugs, and military. These topics frequently included sensitive keywords or phrases, such as land acquisition, death toll, social unrest, poor working environment, food safety, and disputed territories. 

These findings are in line with sociological theory on censorship, which suggests that the elimination of improper political news helps keep ideological purity, the removal of military news reflects a concern over national security, the ban on news covering disputed territories indicates the protection of national interest, and the expurgation of news on unsafe foods is one approach to maintaining social order. Like all modern states, China is wrestling with the impact of the growth in social media. It is aware of just how quickly online media can amplify the impact of events and invite participation, as seen in the Arab Spring movement. In his well-received book Rewire, Ethan Zuckerman, director of the MIT Center for Civic Media, narrates how this movement started with a family’s protest against government corruption in Tunisia, spread beyond one town, and eventually reached over a dozen countries. 

Over a decade before the Arab Spring, China’s leadership had foreseen the potential threat of online media and started developing censorial strategies and tools. What it aims to constrain is the mobilizing power of online media, as indicated by a study conducted by Gary King and his colleagues at Harvard University. 

From the messages deleted from nearly 1,400 Chinese social media platforms, they observed that the state aims to prevent and suppress ongoing and potential collective activities. This is in contrast to the widely held view that first and foremost the Chinese censors target harsh criticism of the state. Hence, on the one hand, social media are censored to prevent mobilization, and on the other hand, news media are censored to eliminate possible triggers for such mobilization. That is why international news was found to have been much less deleted than domestic news from NetEase and Sina, because remote events are not relevant enough to provoke strong reactions among citizens. 

China is not the only country to censor social media. Censorship exists in all societies and all forms of media. For example, there is presently a growing international debate on the ease with which pornography can be accessed online and whether or not this is a danger to children. Websites regarded as promoting Islamic fundamentalism are routinely banned in certain countries. In China, whilst censorship is pervasive, the debate over who controls online access to information and what are its limits has barely begun.

Q&A on Censorship with the Oxford Internet Institute

After presenting my study on China's censorship of online news at the Oxford Internet Institute (OII), I had a great talk with David Sutcliffe, the editor of the OII Policy and Internet Blog, and went through the following questions. The full conversation is published on the blog post titled Uncovering the patterns and practice of censorship in Chinese news sites 
  1. How much work has been done on censorship of online news in China? What are the methodological challenges and important questions associated with this line of enquiry?
  2. You found that party organs, ie news organizations tightly affiliated with the Chinese Communist Party, published a considerable amount of deleted news. Was this surprising?
  3. How sensitive are citizens to the fact that some topics are actively avoided in the news media? And how easy is it for people to keep abreast of these topics (eg the “three Ts” of Tibet, Taiwan, and Tiananmen) from other information sources?
  4. Is censorship of domestic news (such as food scares) more geared towards “avoiding panics and maintaining social order”, or just avoiding political embarrassment? For example, do you see censorship of environmental issues and (avoidable) disasters?
  5. You plotted a map to show the geographic distribution of news deletion: what does the pattern show?
  6. What do you think explains the much higher levels of censorship reported by others for social media than for news media? How does geographic distribution of deletion differ between the two?
  7. Can you tell if the censorship process mostly relies on searching for sensitive keywords, or on more semantic analysis of the actual content? ie can you (or the censors..) distinguish sensitive “opinions” as well as sensitive topics?
  8. It must be a cause of considerable anxiety for journalists and editors to have their material removed. Does censorship lead to sanctions? Or is the censorship more of an annoyance that must be negotiated?
  9. What do you think explains the lack of censorship in the overseas portal? (Could there be a certain value for the government in having some news items accessible to an external audience, but unavailable to the internal one?)

Talk on News Censorship


I'm fortunately funded by the Knight-Mozilla OpenNews Fellowship program to attend a conference on China and the New Internet World organized by the Oxford Internet Institute.  There I will give a presentation on China's news censorship.  I've uploaded the full paper and the slides online, please feel free to download them for more information.  Also, I have more data and preliminary findings unpublished and I'd love to share and discuss them.  My email address is songyan at msu dot edu

Prior and Ongoing Research on Internet Censorship

Internet censorship has been attracting much attention from various academics and institutes.  For example, the Open Net Initiative (ONI) has been constantly testing the availability of websites in 74 countries and rating government control of content related to politics, social issues, Internet tools, and conflict/security (Palfrey, 2010).  The Open Internet Tool Project (OpenITP) surveyed circumvention tool users living in China to understand how they bypass the Great Firewall in hopes of building better tools to serve the needs of internet users in China and other censored regimes (Robinson et al., 2013).

Among the empirical studies focused on online media, Bamman et al.’s (2012) work claimed to be “the first large–scale analysis of political content censorship” that investigates messages deleted from Sina Weibo, a Chinese equivalent to Twitter.  They found 16.25% of posts were deleted after their publication time and recognized some characteristics related to post deletions, including 295 sensitive keywords and the outlying provinces such as Tibet and Qinghai.  Beyond Sina Weibo and on an even larger scale, King et al. (2013) collected data from nearly 1,400 Chinese social media platforms and analyzed the deleted messages with the aid of linguistic software.  In contrast to previous presumptions that its harsh criticism of the government is the target of censors, King et al. found that indeed it's ongoing and potential collective activities that the state aims to prevent and suppress. 

Research Methods in a Nutshell

To our best knowledge, however, censorial practices in online news media have never been studied, not to mention extensively investigated through computing approaches.  Therefore, our study may be the first empirical attempt that systematically examined the news articles deleted from the Chinese cyberspace.  

We developed scripts to collect news articles published on NetEase and Sina, two major news aggregators headquartered in China.  Meanwhile we continuously checked whether or not these articles remained available and we marked a news article as deleted once its link was found broken.  In fact, to make sure that the news story was really deleted due to its content rather than editorial or technical reasons, we searched across the websites for the articles with the same title but under a different link.  Only when duplicates were unavailable did we claim that a particular story was deleted. 

After collecting thousands of deleted news stories, we ran a regression over these data to detect patterns associated with deletion.  The technique we adopted is ReLogit (King and Zeng, 2001a and 2001b), a logistic regression handling rare events data.  This tool was developed by political scientists to analyze rare events, such as wars and coups.  For this reason, this is an appropriate tool for our study because the over deletion rates across the two websites were under 1%, as summarized below. 

Findings and Conclusions

During the course of our study, on each website, about two articles were deleted per day and the overall deletion rate was 0.05% on NetEase and 0.13% on Sina Beijing.

Several similar patterns have been found across the two news portals: 
  • Domestic news had a significantly higher chance of being deleted than international news: twice as likely for NetEase, and about six times for Sina Beijing.
  • News covering Beijing had twice the chance for deletion compared to news covering other places in China.
  • Tibet as a subject matter had little relation with deletion. 
  • National, compared to local, news was significantly associated with deletion for both websites: For NetEase, one and a half times as likely to be deleted, and for Sina Beijing one third times as likely to be deleted.
  • Nature of events was another strong indicator. Compared to neutral stories, for NetEase, positive news had one third the chance to be deleted whereas negative news nearly four times, and for Sina Beijing, negative news had three times to be deleted.
  • Five out of 13 coded news topics were strongly associated with news deletions, including politics, business, foreign affairs, food and drugs, and military, although the strengths varied across the categories and the websites.
From this evidence, we reached the following conclusions: 
  • The two Chinese news portals deleted news with similar patterns.
  • These similarities are translated to the practice of systematic control, the quintessential component of the definition of censorship (Peleg, 1993). 
  • Hence, for the first time, we have confirmed and quantified the online news censorship in China. 

Taboo Words

Beyond news deletion, I've been examining comment deletions as well.  I've created some word clouds with the help of Wordle and highlighted the keywords most commonly found in deleted comments.  They're not included in the paper or the slides. 

These keywords are aligned with our general understanding of taboo topics, such as land acquisition, death toll, social unrest, food safety, pollution, and lamentable work environment.

Comments Prohibited and Suppressed

A second research topic of mine is how comments are manipulated and what patterns are associated with the manipulation.  Various types of manipulation have been observed and they include having commenting function disabled, screening and filtering submitted comments before publication (i.e., pre-censorship), and deleting published comments after publication (i.e., post-censorship).  This topic isn't included in the paper or the slides. 

To make this research topic more understandable, I'll first elaborate on the general practice of Chinese news portals.  Most of the time, news portals welcome and encourage comments because interactions boost web traffic.  However, a small portion of news stories have their commenting feature disabled.  There are two way to implement this function.  On NetEase, a notification is put under a story, informing "commenting is disabled" and the button for commenting is unavailable.  Sina takes a more subtle approach and puts no such a notification and meanwhile users can submit comments as usual but the comments are never displayed on the website.  These are pre-censorship techniques.  As to post-censorship, both websites simply remove comments quietly after their publication.  A third type of manipulative technique is different from passively pre- or post-censoring comments, but to proactively hire Internet commentators, or so-called 50 Cent Party, to propagate orthodox ideas endorsed by the government. 

The following time-series chart demonstrates the first type of comment manipulation, which is to prohibit comments.  In this way, party organs attempt to impose official opinions through one-way communication on issues on North Korea, outlying provinces, controversial territories, major criminal case, and so on.

More subtly, Sina "allows" comments but never shows some of them on the website.  I've figured out how to send parameters to the API to request the numbers of pre-censored comments and drawn the following chart that shows the new stories having no comment at all although their commenting function is "available".

The third time-series chart exhibits the amount of comment deletions on a weekly basis.  The topics found in the deleted comments are fairly aligned with those deleted from news stories.
