原文：

         This plugin for WordPress 1.5.2, 2.0.x and 2.1 asks the visitor making the comment to answer a simple math question. This is intended to prove that the visitor is a human being and not a spam robot.

Example of such question:

This plugin does not require JavaScript or cookies. It uses a special encryption function; the result of the question is being passed via a hidden field. The result is being compared with the value entered by the visitor – after encrypring this value as well.

This plugin can be installed in 5 easy steps:

  • Go to Options / Math Comment Spam, adjust the options and save.
    Important: You need to save the options when you use this plugin the first time or if you have updated from a previous version.

    <?php  /****** Math Comment Spam Protection Plugin ******/ 
( function_exists('math_comment_spam_protection') ) 
{  	$mcsp_info = math_comment_spam_protection(); ?> 
<p><input type="text" name="mcspvalue" id="mcspvalue" value="" size="22" tabindex="4" /> 
<label for="mcspvalue"><small> 
Spam protection: Sum of 
<?php echo $mcsp_info['operand1'] . ' + ' . $mcsp_info['operand2'] . ' ?' ?> 
</small></label> 	<input type="hidden" name="mcspinfo" 
value="<?php echo $mcsp_info['result']; ?>" /> </p> 
<?php } // if function_exists... ?>

    Add this code for example right after the field for the website URL.

    说真的，我很喜欢，相当喜欢这个！
    比所有垃圾评论过滤插件好太多（无论是AK还是SK）。
    呵呵，值得推广，值得推广！特别要称赞插件作者！
    偶尔我也会考虑，还有哪些方法可以让验证码变得更有趣，呵呵。
