  62                               <p>Found the following from <a href="http://www.dvorak.org/blog/?p=2904">Dvorak Uncensored</a>:

  64 <blockquote><p>Most people who run blogs have issues with comment spam in their blogs and there are all sorts of fixes. Marc Perkel at ctyme.com – my host — was floored, he said, when he realized a simple command to the Apache software would kill most of it — and it does indeed work!</p>
  65
  66 <p>Here is the short code running on the ctyme server for my dvorak.org using WordPress-based blogging software. Altering it for other blog software and other blogs should be simple for anyone running Apache.</p>
  67
  68 <div class="code"><pre>
  69 &lt;location /blog/wp-comments-newpost.php&gt;
  70     RewriteEngine On
  71     RewriteCond %{HTTP_REFERER} !^.*dvorak.org/.*
  72     RewriteRule ^.* http://www.ctyme.com/comment-spam.html
  73 &lt;/location&gt;
  74 </pre></div>
  75
  76 <p>Essentially it makes the basic condition for any post rigid: it has to be coming from a link within the blog itself, the “comment” link. Most spam does not.</p>
  77
  78 <p>My spam count on the blog has dropped from 50-100 to 2 per day without any other tricks.</p></blockquote>
