Facebook has purchased Chinese social network Zhanzuo.com for $85 million, according to reports. Facebook has yet to confirm the news, though an unnamed PR flack told the Times of London that Zhanzuo's chief executive Jack Zhang and Mark Zuckerberg know each other and that official news should be expected by the end of the month. Zhanzuo.com has 7 million active members and is reportedly popular among students. Meanwhile, now we have at least one theory why Facebook feels comfortable allowing employers to spy on their employees' private profiles. Facebook could just be preparing to operate in the People's Republic of China, where your privacy really is an illusion. Update: Facebook denies the report.
