MacKinnon will examine one particular type of censorship in China.
Censorship in China is usually categorized in two ways: (1) censorship outside the “great firewall” – filtering of websites outside of China; (2) censorship inside the “great firewall” – deletion of content on domestic or commercial sites; takedown of domestically hosted sites; shut-down of data centers. Circumvention tools that Hal and Ethan just discussed mainly address the former type of censorship.
The difficulty, however, comes with the latter type–when internal sites and servers are shut down. MacKinnon’s work looks at this type of censorship. Research of censorship inside the great firewall is slim; a 2006 study (with MacKinnon) compared which search engine seemed to be removing more or fewer results, and discovered a surprising variety. Search engines were not uniformly censoring in the same way, for the same things–indicating the companies were making internal decisions in reaction to government demands, implementing those demands differently. Nart Villeneuve at The University of Toronto followed up on this study, studying search engine transparency in China.
The study: Given the wide variety of how search engines censored search results, she and her co-researchers hypothesized that blogging services would show a similar variance in their censorship decisions. The study posted content that ranged in sensitivity across 15 different blog services.
Results of study: Censorship varied even more than expected in the blogosphere. A great deal of sensitive content was getting through, but at vary different amounts depending on blogging services. The company with the highest censoring practices censored 60 out of 108 blog posts; the least censoring service only censored one.
The results also revealed different types of censorship behavior: (1) The blogger is prevented from posting at all; (2) post is “held for moderation” (in which case it sometimes would and sometimes wouldn’t appear); (3) post is not visible to public, but only to the author when logged in; (4) published, but then removed within 24 hours; and (5) geo-filtering of sensitive posts (MSN only).
However, very sensitive posts sometimes would get through; yet news agency articles that included names of leaders (e.g. Hu Jintau pep talk to Olympic athletes) would be censored. Why the variation? Potential theories: relationship of local city, provincial, or state officials with blog editors; different methods for implementation.
Conclusions. Domestic censorship is not centralized–it is often outsourced by the government to the private sector, which is itself interacting with choice. The system of “managing” user-generated web content in China follows similar logic and approach as the system for controlling professional news media. While the survey should be improved and applied to a systematic and broader range (e.g. web service company employees), it is a helpful beginning point for additional research in China and in other countries, and has potential activist implications as well–for example, perhaps we should fund more than circumvention tools, and instead on other policies such as raising awareness to bloggers about varying censorship practices.
