Why so much variation?• Instructions to companies from city or provincial State

Council Information Office Internet Section, interpreted differently

• Different methods devised for implementation

• What province/city company is registered in

• Manager/editorʼs relationship with local State Council

• Background and priorities of individual web company managers and editors

• Relationship between company management, investors, and regulatory bodies

Conclusions• Internet filtering (“the great firewall”) is only one part of

Chinese Internet censorship.

• Domestic censorship is not centralized.

• Domestic web censorship is outsourced by government to the private sector.

• Censorship is inconsistent - itʼs usually possible to post your content somewhere, for at least a while.

• The system of “managing” user-generated web content in China follows similar logic and approach as the system for controlling professional news media.

Implications for research “inside the great firewall”

• Need larger-scale studies of domestic web censorship (include chat rooms, social networking sites, instant-messaging, mobile services)

• Unlike automated filtering tests, these tests require manual testing and constant analysis by Chinese speakers with contextual knowledge - it is tedious work requiring attention to detail.

• Need surveys of web service company employees.

• Need surveys of users and bloggers about their experiences.

Implications for activism• Circumvention is important but itʼs not the

solution to the whole censorship problem.

• Educate bloggers and netizens about strategies for successfully disseminating information online about politically sensitive subjects

• Global “user rights” movement demanding greater transparency and accountability by Internet companies on privacy and free expression

Global questions

• Where else in the world is this kind of political censorship by web service companies of user-generated content happening? (Companies in the West already censor for child porn, copyright violations and sometimes hate speech.)

• Will the “Chinese model” - of demanding censorship by companies - spread globally?

• What issues in this vein should the advocacy community be preparing for?

• What further research needs to be done to better understand global trends?
