<p>Since we have this rule very clear in our <a href="https://stats.stackexchange.com/help/on-topic">help center</a> that questions asking for datasets are off-topic, could we include this reason in the off-topic dialog?</p>

<p><img src="https://i.stack.imgur.com/0tDym.png" alt="enter image description here"></p>

<p>The initial suggestion would be to include the current text in the help center and a link to it:</p>

<blockquote>
  <p>Questions about <a href="https://stats.stackexchange.com/help/on-topic">obtaining particular datasets</a> are off-topic, because they are too specialized.</p>
</blockquote>

<p><strong>Possible advantages:</strong></p>

<ul>
<li><p>Currently, I flag such questions for 'moderator attention', but with a customized reason in the off-topic dialog the community would be able to help in a more automatic way. Please, advise me if I should be using another type of flag for this.</p></li>
<li><p>A second advantage would be to spare comments explaining to the OP why the question is off-topic.  </p></li>
</ul>
