title: Blocking Mac / Gecko-20100101 By User Agent?
body: <p>I have a particularly annoying Mac user who is spamming me. This is the user-agent </p>
  
  <blockquote>
    <p>Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:9.0) Gecko/20100101
    Firefox/9.0"</p>
  </blockquote>
  
  <p>Would you suggest to block it via htaccess? Is the following sufficient or is Gecko/20100101 a common user agent?</p>
  
  <pre><code>RewriteEngine On
  RewriteCond %{HTTP_USER_AGENT} Gecko/20100101 [NC]
  RewriteRule ^ - [F,L]
  </code></pre>
