title: Seekport Crawler not blocking
body: <p>Hello I am receiving visit from seekport crawler (just a few but I want to avoid them at all).</p>
  <p>The rule now is:</p>
  <pre><code>RewriteEngine On
  RewriteCond %{HTTP_USER_AGENT} OnalyticaBot [NC,OR]
  RewriteCond %{HTTP_USER_AGENT} &quot;=Re-re Studio (+http://vip0.ru/)&quot; [NC,OR]
  RewriteCond %{HTTP_USER_AGENT} &quot;=Mozilla/5.0 (compatible; Seekport Crawler; http://seekport.com/&quot; [NC]
  RewriteRule ^ - [F]
  </code></pre>
  <p>All this one works, but there is another seekport crawler user agent with this string: &quot;'Mozilla/5.0 (compatible; Seekport Crawler; <a href="http://seekport.com/%27%22" rel="nofollow noreferrer">http://seekport.com/'&quot;</a> (the same but using ' and the begging and at the end).
  Using <code>RewriteCond %{HTTP_USER_AGENT} &quot;='Mozilla/5.0 (compatible; Seekport Crawler; http://seekport.com/'&quot; </code> is not working, the ones with this &quot;new&quot; user agent are not blocked.</p>
  <p>May I have to use any character like &quot;&quot; anywhere?. Maybe the problem is the char ' at the end and the beggining??</p>
  <p>Many thanks</p>
