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.

China Digital Times discovered many new blocked keywords. Some of them have been unblocked since, and some are blocked not just on Weibo. Here's an updated overview:

1.4 million people used FreeBrowser to circumvent the Great Firewall of Turkmenistan

Since 2021, the authorities in Turkmenistan have taken exceptional measures to crack down on the use of circumvention tools. Citizens have been forced to swear on the Koran that they will not use a VPN. Circumvention tool websites have been systematically blocked. Arbitrary searches of mobile devices have also taken place and have even targeted school children and teachers.

The government has also blocked servers hosting VPNs which led to “near complete” internet shutdowns on several occasions in 2022. Current reports indicate that 66 hosting providers, 19 social networks and messaging platforms, and 10 leading content delivery networks (CDNs), are blocked in the country. The government presumably is unconcerned about the negative economic impact that such shutdowns can cause.

Well-intentioned decisions have just made it easier for Putin to control the Russian Internet

This article is in large part inspired by a recent article from Meduza (in Russian).

Since the beginning of the war in Ukraine, Russian users have had problems accessing government websites and online banking clients. Browsers began to mark these sites as unsafe and drop the connection. The reason is the revocation of digital security certificates by foreign certificate authorities (either as a direct consequence of sanctions or as an independent, good will move); without them, browsers do not trust sites and “protect” their users from them.

However, these actions, caused - or at least triggered by - a desire to punish Russia for their gruesome actions in Ukraine, will have long-lasting consequences for Russian netizens.

Digital certificates are needed to confirm that the site the user wants to visit is not fraudulent. The certificates contain encryption keys to establish a secure connection between the site and the user. It is very easy to understand whether a page on the Internet is protected by a certificate. One need just look at the address bar of the browser. If the address begins with the https:// prefix, and there is a lock symbol next to the address, the page is protected. By clicking on this lock, you can see the status of the connection, the name of the Certification Authority (CA) that issued the certificate, and its validity period.

There are several dozen commercial and non-commercial organizations in the world that have digital root certificates, but 3/4 of all certificates are issued by only five of the largest companies. Four of them are registered in the USA and one is registered in Belgium.

Announcing the Release of GreatFire AppMaker

GreatFire (, a China-focused censorship monitoring organization, is proud to announce that we have developed and released a new anti-censorship tool that will enable any blocked media outlet, blogger, human rights group, or civil society organization to evade censors and get their content onto the phones of millions of readers and supporters in China and other countries that censor the Internet.

GreatFire has built an Android mobile app creator, called “GreatFire AppMaker”, that can be used by organizations to unblock their content for users in China and other countries. Organizations can visit a website ( which will compile an app that is branded with the organization’s own logo and will feature their own, formerly blocked content. The app will also contain a special, censorship-circumventing web browser so that users can access the uncensored World Wide Web. The apps will use multiple strategies, including machine learning, to evade advanced censorship tactics employed by the Chinese authorities.  This project will work equally well in other countries that have China-like censorship restrictions. For both organizations and end users, the apps will be free, fast, and extremely easy to use.

This project was inspired by China-based GreatFire’s first-hand experience with our own FreeBrowser app ( and desire to help small NGOs who may not have the in-house expertise to circumvent Chinese censorship. GreatFire’s anti-censorship tools have worked in China when others do not. FreeBrowser directs Chinese internet users to normally censored stories from the app’s start page (

Apple, anticompetition, and censorship

On July 20, 2020, GreatFire wrote to all 13 members of the Subcommittee on Antitrust, Commercial and Administrative Law of the U.S. House Committee on the Judiciary, requesting a thorough examination into Apple’s practice of censorship of its App Store, and an investigation into how the company collaborates with the Chinese authorities to maintain its unique position as one of the few foreign tech companies operating profitably in the Chinese digital market.  

This letter was sent a week before Apple CEO TIm Cook will be called for questioning in front of the Subcommittee on Antitrust, Commercial and Administrative Law. The CEOs of Amazon, Google and Facebook will also be questioned on July 27, as part of the Committee’s ongoing investigation into competition in the digital marketplace.

This hearing offers an opportunity to detail to the Subcommittee how Apple uses its closed operating ecosystem to not only abuse its market position but also to deprive certain users, most notably those in China, of their right to download and use apps related to privacy, secure communication, and censorship circumvention.

We hope that U.S. House representatives agree with our view that Apple should not be allowed to do elsewhere what would be considered as unacceptable in the U.S. Chinese citizens are not second class citizens. Private companies such as Apple compromise themselves and their self-proclaimed values of freedom and privacy when they collaborate with the Chinese government and its censors.

Apple Censoring Tibetan Information in China

Apple has a long history of censorship when it comes to information about Tibet. In 2009, it was revealed that several apps related to the Dalai Lama were not available in the China App Store. The developers of these apps were not notified that their apps were removed. When confronted with these instances of censorship, an Apple spokesperson simply said that the company “continues to comply with local laws”.

In December, 2017, at a conference in China, when asked about working with the Chinese authorities to censor the Apple App Store, Tim Cook proclaimed:

"Your choice is: do you participate, or do you stand on the sideline and yell at how things should be. And my own view very strongly is you show up and you participate, you get in the arena because nothing ever changes from the sideline."

In the ten years since Apple was first criticized for working with the Chinese authorities to silence already marginalized voices, what has changed? Apple continues to strictly follow the censorship orders of the Chinese authorities. When does Tim Cook expect that his company will help to bring about positive change in China?

Based on data generated from, Apple has now censored 29 popular Tibetan mobile applications in the China App Store. Tibetan-themed apps dealing with news, religious study, tourism, and even games are being censored by Apple. A full list of the censored apps appear below.
