Facebook was banned in 2009, after the biggest terrorist attack in China, so-called July 2009 Urumqi riots [1] , which happened in Xinjiang Urumqi. More than 200 peoples died in this attack, and most of them are innocent citizens, including two of my schoolmates. You might wonder what is the relationship between this terrorist attack and Facebook. The only reason is the terrorists planned this attack on Facebook and Facebook refused to disclose the informations of organizers. Did Facebook do the right thing? I don’t know, but we must ensure that such a terrorist attack will never happen again in Xinjiang province. That’s why we banned Facebook.
