So much for the free flow of information. China has a long history of internet censorship, often soliciting versions of popular services such as MySpace that fit within their narrow definitions of acceptable content. The latest example comes in the form of a blanket ban of Yahoo’s photo sharing service Flickr. Chinese users have been unable to view images on the popular site since last week. The ban follows the disappearance of a number of images of the 1989 Tienanmen Square massacre. There’s no official word from the Chinese government, but Yahoo’s Hong Kong office has confirmed the ban. Censoring the internet and erasing your national history at the same time? Two birds with one stone, we suppose.
