Microsoft reportedly censors searches for politically sensitive Chinese personalities
 

You may find it hard to search for people considered politically sensitive in China if you're using Bing — even if you're in the United States. The Citizen Lab, a research lab based at the University of Toronton's Munk School, has analyzed Bing's autosuggestion system and found that names of Chinese party leaders and dissidents don't automatically show up like they usually would when you start typing. They're apparently the second largest category of names censored by autosuggest, next to names related to pornography and eroticism.
