GreatFire May: Google and Sina Adapt, The Great Firewall Strikes Back

After analyzing our May data, which now covers more than 30,000 URLs, we can confidently say that the month of May was uneventful. Few major websites were blocked or unblocked. Perhaps this lack of activity was related to leadership change in China (and not just at the very top - see Rumors say China's chief internet censor replaced. While the Great Firewall didn't change much, Google and Sina, in very different ways, both took important steps in trying to deal with the pervasive censorship.

Google Strikes - The Great Firewall Hits Back

"We have observed that searching for certain keywords on Google from within mainland China will often lead to a temporary service disruption." 
Google Support, May 31, 2012.

Starting on May 31, Google displayed a warning message to users from China if they enter any of the many keywords blocked by the Great Firewall. Users could choose to continue the search which would most likely result in the connection being reset for a minute or so. Or they had the possibility to edit the search query and find another, non-blocked, way of searching for the same thing.

For the 16.7% of Chinese web users that use Google, the immediate effects of this was that the censorship became more transparent. To make it even more transparent, Google could choose to publish the list of blocked keywords. Meanwhile, we've reverse-engineered the full list. You can also browse our own database of keywords blocked on Google. Another effect was that the user experience improved. Since a reset connection means that you can't use the service at all for about a minute, a warning message is much more convenient. Furthermore, the suggestion function that offers autocompletion of common searches worked better. Try typing "tiananm", for example.

However, after a month of relative inactivity, this got the GFW team to strike back. Within a day, they disabled the new Google feature by blocking the javascript file that contains the code altogether. This of course makes us wonder what Google's next move will be. It would be very easy to rename the file or to embed it on the html page making it more difficult to selectively block features.

Going forward, there is much more that Google can do. Rather than just informing users that a search query has been censored, they could offer ways to get around it. The most obvious one would be to redirect users (automatically or manually) to the encrypted version of Google which is still not blocked in China (

The fact that this functionality was rolled out, and not just on Google Hong Kong but actually any Google search engine that is accessed from China, shows that Google is actively working on ways to get around censorship in China. For more on this exciting game, read Google Confronts the Great Firewall on Foreign Policy and the announcement on the Google Search Blog. was blocked in May which is the only major Great Firewall change during the month which involved Google.

How to get your account closed on Sina Weibo

On May 29, Sina Weibo announced a new user-points system to regulate users (original, interpreted by ZDNetAsia). The concept is that each Weibo user will be given 80 points to start with. Any behaviour deemed inappropriate by censors will cause points to be deducted. If the user reaches 0 points, his or her account will be closed.

Just like with the user contract announced last month, the description of what is allowed and not is very general. So what is a user who wants to get their account closed to do? Here are a few tips:

  1. Post a lot of tweets containing these keywords that are all blocked on Sina Weibo.
  2. For more efficiency, check out these keywords that are blocked not only on Weibo but also on Baidu and Google.
  3. Get some inspiration by checking out copies of thousands of Sina Weibo posts that have been deleted.

In other Weibo news, weibo: 天安门 was briefly unblocked on May 21 but has otherwise been fully blocked before and after. weibo: 郭金龙 was unblocked during the second half of May and has stayed that way since.

Bing Bests Baidu Censorship


Independent research from Xia Chu has shown that, in addition to non-China content, Bing censors a vast amount of content that is hosted inside China and which is not censored by China-based internet companies like Baidu. After communicating our issues with Microsoft, Bing removed certain censorship rules (kudos to Bing), but much work remains to be done.

We recently called for Microsoft to release its transparency report for Bing (as have others - full disclosure, Rebecca sits on our advisory board).  Microsoft has yet to respond to this request. But Xia’s independent research of Bing’s China censorship policy could be regarded as a de facto transparency report for the search engine.

In this thorough study, the results of which we have verified, Xia examined Bing's SERP (search engine results page) for over 30,000 sensitive and nonsensitive query terms, and launched these queries from both inside and outside of China. Comparing and examining these results, plus querying with special search operators, reveals unprecedented detail on Bing's China filtering practices.

The main findings from Xia’s research include:

  • Bing has a list of “forbidden” terms where no results are shown. 139 such terms have been identified.

  • Bing has a blacklist of websites that it never shows to China users. 329 such websites are identified. (5 have been lifted after our communication with Microsoft.)

Setting Bing's Broken Record Straight

We can also now trace complicit Bing Chinese censorship back to 2009 as highlighted by Nicholas Kristof. It looks like Microsoft has indeed changed its censorship mechanism after our research made headlines this week. But Bing is still seriously flawed on two fronts: its algorithm favors pro-Chinese government websites by default on all search terms in simplified Chinese and their front end mistakenly delivers explicit censorship of search results on some search terms for users from all over the world.

No error here: Microsoft deploying Chinese censorship on global scale

Microsoft says: “The results themselves are and were unaltered outside of China”. This is simply not true.

Bing practicing Chinese censorship globally

Our latest research indicates that Microsoft’s search engine Bing is censoring English and Chinese language search on its home page in order to exclude certain results. We have also noticed that Bing is practicing subtle censorship with search results. In both instances, Bing is filtering out links and stories that the Chinese authorities would deem damaging.

Massive blocking of foreign media in China

After Tuesday’s report Leaked Records Reveal Offshore Holdings of China’s Elite by ICIJ, China blocked a number of major newspaper websites. All websites below were blocked after publishing copies of the original report. They're all listed as the publishing partners for “Chinaleaks” stories on ICIJ's website. The Great Firewall rarely blocks non-Chinese websites. Many of them have published the Chinese version of the report which probably explains the unusual development.
