12月21日，一份CSDN网站用户数据库被人在网上公开，其中超过600万个注册邮箱帐号和对应明文密码。这些数据泄露后，虽然对于网民的安全造成极大的威胁，但也为研究中国网民的上网习惯提供了绝佳的数据样本，以下是某程序员使用Python写了个小脚本，对互联网上流传的用户数据做了一下分析，颇有心得。
以下数据来自7K7K、178、CSDN、人人网、嘟嘟牛、多玩泄漏的用户信息，剔除无效信息后将近3800万条，因为样本巨大，统计结果也比较具有说服力。在此我谨代表广大网民“感谢”以上网站对本次统计活动的支持。
注：如果你的统计结果与我的有微小差异，这是很正常的，因为每个人筛选数据的方式不尽相同。
中国网民最喜欢用什么邮箱？
注：百分比相对于前十名，163和126已经合并。
我们可以看到，网易和腾讯几乎瓜分了80%的市场份额，在本次统计中两者差距在10万以内。
以下是前100名的具体数据：

中国网民喜欢用什么密码？
注：百分比相对于前十一名，全部转换为小写再统计。
这里的密码之所以全部转换为小写，只是因为我的老爷机内存无法承受过于巨大的数据规模。实际上，在CSDN泄密时，前100名就全部是小写密码，因为样本巨大，这样做可以认为对结果没有影响。

有多少中国网民用纯数字作为密码？
注：百分比相对于所有样本
很遗憾，45%之巨（大约1700万）的被统计用户选择了纯数字作为他们的密码，这反应出国内大多数网民安全意识还相当淡薄。
以下是具体数据：
Rank:0 IsNum:False Count:20980399
Rank:1 IsNum:True Count:16889922
选择纯数字作为密码的网民中，密码的长度一般是多少？
注：百分比相对于前十一名采用纯数字作为密码的样本
这里的结果完全符合笔者的预期，6位数字多半是生日，8位、7位和9位应该有QQ号的功劳，而选择11位密码的多半是直接使用的手机号。
