&gt; On the other hand, I wonder if there are sites which use JS to hide the content and display a &quot;turn off JavaScript to view this article&quot;, or &quot;install adblocker to view this article&quot;...<p>I&#x27;ve seen something roughly like this. If a site says &quot;do something&quot; in order to view content, like subscribe or bend over, I&#x27;ll turn off CSS and sometimes see the content.
