<p>In the suggested edits queue, I found <a href="https://stats.stackexchange.com/review/suggested-edits/180557">a post</a> referrencing a textbook, and its edit which added a download link to the mentioned textbook. Assuming the following:</p>

<ol>
<li>The uploaded version of the textbook is not a legal copy (i.e. the author of the referrenced blog has no rights to publish the book on his website).</li>
<li>Neither the question author nor the edit author are anyhow connected to the blog page containing the download.</li>
</ol>

<p>Is it okay to approve such edit?</p>

<hr>

<p><strong>Note:</strong> Whether the assumptions hold in the incriminated case is a different story. To simplify the question, let's just assume they are true.</p>
