Micro bloggers：have you ever compared the number of fans on your Sina Weibo or Tencent micro blog with those of your friends ?Don’t imagine you have more fans just because your number is bigger——some of them might be “zombie fans”，or fake(假的)followers．
That’s what Chen Chuanliang ，creator of Leijian Network，found when he bet against his friend several months ago．Chen，who used to do data mining for Microsoft Asia Research Institute，discovered that there were far more invalid(无效的)micro blog accounts than he had imagined．
Later Chen picked 1 0 users on Sina Weibo and analyzed their statistics．Kai-Fu Lee，the former CEO of Google China，who’s on Chen’s list of research，posted a message on his micro blog after he found out that he had more than 1 million fake fans(out of about 5 million)，joking“I have 1 million zombie fans ?If united，we can finally defeat those plants．”
According to a report by S Weekly in March，zombie fans on micro blogs are defined as invalid accounts signed up by network companies for the purpose of increasing the number of fans for certain users and getting them more attention．
And this kind of fake followers are also very much alive on Western social networks such as Twitter and Facebook ．
The Financial Times reported in August，that Newt Gingrich，a Republican candidate in the US presidential election，bought about 80 percent of his 1．3 million Twitter followers and tried to use them as help in his campaign．
Now there are also business deals through which users can get hundreds of thousands of fans for their micro blog accounts，by paying a small amount of money．
“We have been working to find ways to block or delete those invalid accounts，”Mao Taotao，a spokesperson for Sina Weibo told S Weekly.
“But as the fake accounts grow so fast，they’re going to be here for a while．
