<p>(Speaking in general terms rather than to the specifics.)</p>

<p>If someone copies <em>part</em> of an answer but correctly references it (credits the original author) and quotes the part they took (typically using a blockquote), that's usually fine unless that's essentially the entire answer.</p>

<p>There's several things to do if someone copies a whole answer:</p>

<ol>
<li><p>dealing with the copied answer</p>

<ul>
<li><p>attempt to guide the poster (e.g. comment to let them know that this is not a suitable thing to do, and explain how to quote and reference what they need, or to flag as duplicate if the question is a duplicate), and</p></li>
<li><p>either edit to quote and credit (where suitable), or </p></li>
<li><p>vote to delete or flag to delete or flag to convert to a comment (e.g. if the copied answer is only somewhat relevant rather than a real answer)</p></li>
</ul></li>
<li><p>a copied answer typically indicates a duplicated question; if that's the case</p>

<ul>
<li><p>flag as duplicate, vote to close as duplicate, or mark as duplicate if you have a relevant gold tag badge if this is the case</p></li>
<li><p>if the question is essentially an exact duplicate and has very good answers that would therefore answer the original that it's a duplicate of, you may want to ask for a merge; flagging to close as a duplicate (etc) as above is still the first thing to do.</p></li>
</ul></li>
</ol>
