The so-called unintentional, the listener intentionally.

The premise is: a netizen found a medium-sized e-commerce site BBS Member list page is open.

The process is: The Netizen will this forum as not pay attention to user privacy negative example and write into the soft text.

Coincidence: Most of the accounts in this forum are registered by email.

The pain Heart is: The Forum administrator until about one months to resolve this loophole.

Yunfei technical content is not very high, so with the Thunderbolt (Xunlei) to get 10,000 of the Web page contains e-mail files. Because the Web page is a unified template, the cloud fly retarded Unlimited use of Dreamweaver search and replace features to remove the extra HTML tags.

This time I contacted the "regular expression", and began to worship the great of the regular style. With the regular-style tool, data processing and statistics have become extraordinarily easy.

In the near 160,000 email address for statistical analysis of the process, found some interesting.

Total extracted to "*@163.com" 44,000 times; *@126.com "20,000 times;

"* @sina. com" 10,000 times; * @sohu. com "4,000 times;

"* @qq. com" 39,000 times; * @yahoo. com department "12,000 times.

The above data shows that the power of QQ mailbox can not be belittled, almost will shake NetEase mailbox dominant position, also explained 4 big portal, Sohu's mailbox is not big Mody is liked, also explained Yahoo mailbox in "The Thin dead camel bigger than the horse" stage, although Yahoo China several easy its main, But it does not prevent everyone to use the previous for internationalization and registered Yahoo Mail.

From the data also extracted 9,000 MSN (Hotmail mailbox), 4,000 gtalk (Gmail mailbox), 1000 phone numbers (139 mailbox), of course, there are nearly 40,000 QQ (QQ mailbox).

If you adopt ' *196 ', ' *197 ', ' *198 ', ' *199? ' To match the users who were born in the 60, 70, 80, and 90. You can get 200 forums, 900 whenever, close to 5,000, and 700.

Another, can be extracted to the full date of birth of the email number of 2000. The mailbox name contains a full birthday, only to show that the user is a computer rookie, so their mailbox password may also be very simple, such as may be their home phone number or license plate.

Of course, there are many mailbox names containing such as 2003, 2004, 2008, such as the year, which indicates that the mailbox may be registered in 2003 or 2004, or this year for him by special meaning (such as 2008, the Olympic Games).

Many people use hyphens (_) or minus signs (-) in their mailbox names because of the duplicate name. About 13,000 people used hyphens, while only 3,500 were using the minus sign. It is possible that even characters are more in line with international practice, and most likely, some registrars only allow the use of letters, numbers, and hyphens to register.

Even we can find 200 teachers, because they use the edu.cn end of the mailbox, 50 government officials, they use the gov.cn end of the mailbox, one or even my water colleagues, because he came from the Ministry of Resources @mwr.gov.cn.

The above data only have statistical and demographic significance.
