title: Google map api v3 + Google has disabled use of the Maps API for this application
body: <p>Just came across this error today intermittently:</p>
  
  <pre><code>Google has disabled use of the Maps API for this application. See the Terms of Service for more information: http://www.google.com/intl/en-US_US/help/terms_maps.html.
  </code></pre>
  
  <p>somehow when I refresh the page, the map comes back again. I thought if it's a violation, it would have revoke the key permanently and not allow the map loads using this key anymore. Also, the error always happens at page load. I have yet to hit the error if it's already successfully loaded. I briefly read through the terms but couldn't find anything suspicious. Anyone can advise on how to go about this error? Should I be checking for some js error or the map terms? Thanks.</p>
  
  <p>This is how the map script looks like:</p>
  
  <pre><code>&lt;script src="http://maps.google.com/maps/api/js?v=3&amp;sensor=false&amp;libraries=places&amp;key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" type="text/javascript"&gt; &lt;/script&gt;
  </code></pre>
