I use the spare time to write the Northeast Manufacturing network, the website is 08 month official operation, just started the time, the website traffic is very small, but Baidu and Google to the website's collection is more normal, has the new data basic included. But not a thing, when I advertised, with a number of mechanical manufacturing site after the link, followed by a new user registration and data, spam software bulk registration and mass 17830.html "> Spam data also visit my website." Affected by their influence, the major search engines on the information collected are a lot slower, basically a week to update a few data.

This question once bothered me one months, finally I personally tried a few mass software, just found. Mass device is filled in the information after a good, by the software group, the release of each site to encounter the verification Code program, the system will automatically read the Code program files, and will generate the verification code displayed by the information released by hand.

Although I have changed a lot of programs, and the Verification Code program has been modified, to the need for the human brain to calculate the result of verification code addition, but still can not effectively shield garbage data, after a variety of search and research I found that the garbage software mass can read the verification code, even if you verify the code algorithm is very complex, but also added a lot of interference elements , they are equally able to read the data and ask the sender to write the message manually. That is, no matter how complicated you write the session validation picture program, they can read the software, and let the bulk information of the manual input verification code.

However, there is always a solution to the problem, I by adding a date selection box on the registration page, ask for registration to choose today is the day of the week, and the page to submit validation is also verified today is the day of the week. This effectively avoids the mass software automatically read the verification code problem, to send data must be through the Site page can be.

After the program modification, in recent time, the rubbish data basically did not have, above is my method, hoped to have the help to the general stationmaster. Effect Address: http://dbzz.net/userinfo/user_reg_com.php
