Reuters hat ein spannendes Interview mit chinesischen Netz-Zensoren geführt
Sina's computer system scans each microblog before they are published. Only a fraction are marked as sensitive and need to be read by a censor, who will decide whether to spare or delete it. Over an average 24-hour period, censors process about 3 million posts.
A small number of posts with so-called "must kill" words such as references to the banned spiritual group Falun Gong are first blocked and then manually deleted. Censors also have to update lists of sensitive words with new references and creative expressions bloggers use to evade scrutiny.
For most posts deemed sensitive, censors often use a subtle tactic in which a published comment remains visible to its author but is blocked for others, leaving the blogger unaware his post has effectively been taken down, the former censors said. Censors can also punish users by temporarily blocking their ability to make comments or shutting their accounts in extreme cases.
