| | Empirical Analysis of Internet Filtering in China |
 | | The Internet poses a new challenge to such censorship, both because of the sheer breadth of content typically available, and because sources of content are so often remote from Chinese jurisdiction, and thus much more difficult to penalize for breaching restrictions on permissible materials. |
 | | Further, while the government-connected Internet Society of China (not a chapter of the international Internet Society) has asked Internet service providers and content creators to sign a pledge including self-filtering, few official statements document the existence of government-maintained web filtering, much less the criteria employed and thresholds necessary to elicit a block. |
 | | China's Internet filtering efforts remain opaque, and in the absence of government cooperation or admission of filtering methods, data probing of the sort used in our study remains a useful tool in determining the scope of filtering. |
