How are these results reconciled with well-documented censorship of any posts containing specific words? I've personally seen social media posts with any mention of events like Tiananmen or political leaders blocked (often automatically by software), and a Chinese friend discovered she couldn't text the number '64' around June 4th (she was actually trying to send an address). You can try it for yourself on a site like Renren (www.renren.com), just try posting something with the words 天安门 (Tiananmen), 习近平 （Xi Jinping, China's current President), or 周永康 (Zhou Yongkang, former PSC member). The Chinese version of Skype (actually Skype, not a clone) even blocks words like 'fuck' (see: http://www.nartv.org/mirror/breachingtrust.pdf http://www.nartv.org/mirror/breachingtrust.pdf)
