prevent bots / scrappers executing javascript to get output : <p>I see allot about Cpatcha's and Submission forms / methods to block bots and content scrappers / leechers but nothing about blocking those who take the entire JavaScript contents and execute it to obtain and view what it is outputting.</p>

<p>Is it possible to prevent bots executing JavaScript to obtain the output.</p>

<p>I have looked at if statements within JavaScipt checking screen resolutions, keyboards, mouse, touch screens basic human required functions etc but it is a hard area to find information on.</p>

<pre><code>if (bot){ //don't execute Javascript don't let the bot get the real output.
return;
}
</code></pre>
