Adds an ASP code for Anti-Spam comments to despise spam.

I have recently activated this service. I have been plagued by spam comments and have not found a good solution. In fact, WordPress has some powerful plug-ins to prevent spam, such as akismet, but this only makes me envy, so I have been searching for a relatively good solution recently.

Today, we can see a good method on bigik.cn. bigik uses user verification in the form of addition operations to solve this problem. The method is now reproduced. Of course, this method is not perfect. I found that some spam will come in.

Usage:
ProgramCode Copy codeThe Code is as follows: function getnum ()
Dim quesionnum
Quesionnum = 7' total number of problems. To add a problem, modify this value first.
Dim codeindex
Codeindex = 0

Dim quesionarray (100)
Dim answerarray (100)

Quesionarray (0) = "= 1 + 1" 'list of questions and answers, which can be modified by yourself
Answerarray (0) = "2"
Quesionarray (1) = "= 2 + 2"
Answerarray (1) = "4"
Quesionarray (2) = "= 3 + 4"
Answerarray (2) = "7"
Quesionarray (3) = "= 2 + 4"
Answerarray (3) = "6"
Quesionarray (4) = "= 1 + 2"
Answerarray (4) = "3"
Quesionarray (5) = "= 2 + 3"
Answerarray (5) = "5"
Quesionarray (6) = "= 4 + 4"
Answerarray (6) = "8"

Randomize
Codeindex = int (quesionnum * RND) + 0)
Session ("getnum") = answerarray (codeindex)
Getnum = "<span style =" "margin-Right: 40px;" ">" & quesionarray (codeindex) & "</span>"
End Function

Call method:Copy codeThe Code is as follows: <% response. Write getnum () %>

Other modification suggestions:
The question can be set to any question of addition, subtraction, multiplication, division, or other text questions, such as "987x654 = ?" "How many ethnic minorities are there in China ?" Wait, don't let the viewer fail to answer: P.
We recommend that you reduce the width of the verification code input box and set the maximum number of characters to 2.
