从垃圾邮件机器人隐藏电子邮件的有效方法 [英] Effective method to hide email from spam bots

问题描述

 < a href = admin [at] example.com
 rel =nofollow
 onclick =this.href ='mailto：'+'admin'+'@'+'example.com'>与我联系< / a> 
  

你觉得怎么样？是否有效？你也知道或使用了什么其他方法？

解决方案

这是我使用的方法，服务器端包括例如<！ - ＃include file =emailObfuscator.include - > 其中 emailObfuscator.include 包含以下：

 <！ -  // http://lists.evolt.org/archive/Week-of-Mon -20040202 / 154813.html  - > 
< script type =text / javascript> 
 function gen_mail_to_link（lhs，rhs，subject）{
 document.write（< a href = \mailto）; 
 document.write（：+ lhs + @）; 
 document.write（rhs +？subject =+ subject +\>+ lhs +@+ rhs +< \ / a>）; 
} 
< / script> 
  

要包含地址，我使用JavaScript：

 < script type =text / javascript> 
 gen_mail_to_link（'john.doe'，'example.com'，'关于你的网站的反馈...'）; 
< / script> 
< noscript> 
< em>受JavaScript保护的电子邮件地址。激活JavaScript以查看电子邮件。< / em> 
< / noscript> 
  

由于自2005年以来我一直通过Gmail收到邮件，垃圾邮件几乎是一个非问题。所以我不能说这个方法有多有效。您可能想阅读此研究 （虽然它很旧）生成了这个图：

On my homepage, I'm using this method to hide my email from spam bots:

<a href="admin [at] example.com"
   rel="nofollow"
   onclick="this.href='mailto:' + 'admin' + '@' + 'example.com'">Contact me</a>

What do you think about it? Is it effective? What other methods do you know or use?

解决方案

This is the method I used, with a server-side include, e.g. <!--#include file="emailObfuscator.include" --> where emailObfuscator.include contains the following:

<!-- // http://lists.evolt.org/archive/Week-of-Mon-20040202/154813.html -->
<script type="text/javascript">
    function gen_mail_to_link(lhs,rhs,subject) {
        document.write("<a href=\"mailto");
        document.write(":" + lhs + "@");
        document.write(rhs + "?subject=" + subject + "\">" + lhs + "@" + rhs + "<\/a>");
    }
</script>

To include an address, I use JavaScript:

<script type="text/javascript"> 
    gen_mail_to_link('john.doe','example.com','Feedback about your site...');
</script>
<noscript>
  <em>Email address protected by JavaScript. Activate JavaScript to see the email.</em>
</noscript>

Because I have been getting email via Gmail since 2005, spam is pretty much a non-issue. So, I can't speak of how effective this method is. You might want to read this study (although it's old) that produced this graph:
