<p>As for me, the whole idea about <a href="https://stats.stackexchange.com/questions/tagged/self-study" class="post-tag" title="show questions tagged &#39;self-study&#39;" rel="tag">self-study</a> is that people are working on some exercise and are looking for some <em>hints</em> since they are stuck. Copying-and-pasting a textbook exercise produces <strong>off-topic</strong> rather then self-study questions. </p>

<p>In my opinion, any new user who and pastes a homework question should be encouraged to show some effort in solving it, or at least to point out where they got stuck and what kind of hints are asked for. Applying the <a href="https://stats.stackexchange.com/questions/tagged/self-study" class="post-tag" title="show questions tagged &#39;self-study&#39;" rel="tag">self-study</a> does not make a copy-and-pasted question a self-study question... In such cases I'd rather vote to close it, rather than re-tagging. </p>
