title: "Extreme" CPU usage on Drupal site, account disabled as a result
body: <p>I suddenly got a spike in CPU usage on shared hosting and my website has been taken offline for the past 48 hours. I have already tried the following, and it did not help (or only a bit):</p>
  
  <ul>
  <li>Updated Drupal 7 and all modules to the latest version</li>
  <li>activated CloudFlare</li>
  <li>disabled any unused modules</li>
  </ul>
  
  <p>Caching was already on (min cache lifetime: none; expiration cached pages: 1 hour; bandwidth optimization: all options checked). I had no problems before, and visitor numbers have remained fairly constant at 1500-2000 a day. Could it be hacked? Spam? The logs only show lots of Google bot "access denied" activity, but somehow doubt that can take the site down.</p>
  
  <p>Thanks in advance for any advice!</p>
