From Global Post:
"Last week, the internet giant rolled out a new feature on its Hong Kong-based search site that warns users when a term they are searching for will be blocked, resulting in being shut out from Google for a minute and a half.
Because Google does not comply with Chinese censors — as China’s largest search engine, Baidu, does — the government automatically blocks a wide range of words, including some apparently benign and non-political terms. “Yangtze River,” for example, lands users in the penalty box because of its similarity in Chinese to the name for former president Jiang Zemin...
...Dave Lyons, a Beijing-based information science researcher, notes on his blog that most Chinese users who really want to find banned information already know how to use VPNs and other tools to circumvent censorship."
