主题：【原创】谁下西西河？最新数据分析 -- 青牛甲

根据一个美国网站的资料（小鱼儿估计是根据ip地址推人口调查数据），关于谁下西西河有出如下结论：

在美国这里下西西河的每月有2千多人，其中70%男性。下河者的岁数：53%在18-34之间，21%的在35-49岁之间。看来西西河吸引的是成熟稳健的朋友。下河者70%是亚洲人。(奇怪：鬼佬也上西西河？）64%的下河者有孩子。关键一点，下河者年收入两级分化:51%赚不到3万（估计是飘洋过海大话西游的留学生），32%收入在10万以上（估计是铁手、观天之流了）。另外，47%的下河者有研究生文凭，我相信这点是很准的。（估计是根据大学研究生院的ip地址猜的）。

该网站总结陈词：西西河是一个专门吸引高学历的亚洲男性的网站（听上去西西河的受众和某些高级xxx网站很重合）。

口说无凭，该网站关于西西河的分析在这里。

如果觉得好，大家给朵花吧。最近送花太多，经验不足，大家行行好给补补。

如果是真的，想想这太可怕了。。

Quantcast is a Web site that is based on viewing the statistics of other Web sites. Quantcast Corporation's prime focus is to analyze the Internet's Web sites in order to obtain accurate statistics. Like Alexa, Quantcast rates Web pages by ranks. However, Quantcast does not require a tool bar to be installed upon one's browser to obtain statistics. Instead participating websites voluntarily insert Quantcast HTML code inside Web pages they wish to have included in statistics. This code allows Quantcast to keep track of the traffic directed towards those Web sites.[1] Using this mechanism Quantcast can provide thorough details about Web pages created by participating publishers. Some of this information includes, for example, whether the Web page viewer is a male or female, whether the average viewer makes $30,000 USD annually or $100,000 USD annually, the age group of the viewer and the amount of U.S. homes the Web site reaches. This information is provided by inference: comparing and correlating the information received from one participating publisher with another. The inferences are possible because the Quantcast code causes the user's browser to access Quantcast's servers, at which time they can log the user's IP address and information Quantcast places in cookies that are stored in the user's browser. The cookies significantly aid in making inferences. Quantcast also provides affinities revealing other popular sites that the average viewer browses. This is possible by tracking "referrer" information that is normally included as part of every HTTP request made by the user's browser. For instance a person browsing a page on Quantcast aimed towards music might also browse sites based on music downloads.[2][3]

上花！

我也正这么想呢？根据IP地址还能得出来收入？

注册的时候好像也不用填这种信息吧？

谢谢SIOUX的补充。

照文字看来，这家Quantcast应该做得很专业了。

不过看完还真让我感觉会有点被追踪的感觉。

如果这些个人信息不能很好的被保护的话，那后果还真是不可想象呢。

想想在国内，我们平时的手机会收到多少条垃圾短信？诸如此类的事情，还真是挺多的。

不知道国外会不会也有私人信息被泄露和滥用的事情。
