Consider the Google search that started this:<p>&quot;not for public release filetype:pdf&quot;<p>That&#x27;s a pretty flagrant attempt at accessing confidential documents. It isn&#x27;t like someone googles &quot;how to catch a roadrunner&quot; and accidentally downloads confidential Acme documents. This is a full on attempt to find poorly secured documents.<p>Now, consider what Google does. It runs bots (that respect things like robots.txt) and then publish links to everything that they can find.<p>Maybe I&#x27;m missing some subtlety, but I don&#x27;t understand how these are similar. Can you explain yourself further?
