&gt; How could you know it&#x27;s an illegal or legal source anyways when clicking on a link?<p>It&#x27;s often pretty easy to tell. For instance, whenever I&#x27;m thinking of seeing a movie that is currently or soon to be in theaters and Google for reviews, I get a bunch of links to sites purporting to have the movie available for download. It does not take a genius to figure out that these are not legal copies.
