I have written a post at inmediahk.net on the application of filtering in Hong Kong by flickr which is not based on jurisdiction but on localized yahoo account(zh). Moreover, its censorship is stricter that local law which allows access of adult information with a warning message. The present flickr filter doesn't allow Hong Kong yahoo user to access “safe off” section. Of course user can always shift to a foreign yahoo account (such as Taiwan and U.S).
