<p>Absolutely.</p>

<p>It seems that the people at ubuntuask.com have a different (meaning "wrong") interpretation of the license.</p>

<p>It actually says not only that attribution is required, but that attribution is required <strong>in the manner specified by the author or licensor</strong>, which - on Stack Exchange - includes this:</p>

<blockquote>
  <p>So let me clarify what we mean by attribution. If you republish this
  content, we <strong>require</strong> that you:</p>
  
  <ol>
  <li><strong>Visually indicate that the content is from Stack Overflow, Meta Stack
  Overflow, Server Fault, or Super User</strong> in some way. It doesn’t have to
  be obnoxious; a discreet text blurb is fine.</li>
  <li><strong>Hyperlink directly to the
  original question</strong> on the source site (e.g.,
  <a href="http://stackoverflow.com/questions/12345">http://stackoverflow.com/questions/12345</a>)</li>
  <li><strong>Show the author names</strong> for
  every question and answer Hyperlink each author name directly back to
  their user profile page on the source site (e.g.,
  <a href="http://stackoverflow.com/users/12345/username">http://stackoverflow.com/users/12345/username</a>)</li>
  <li><strong>Hyperlink each author name</strong> directly back to their user profile page on the source site (e.g., <a href="http://stackoverflow.com/users/12345/username">http://stackoverflow.com/users/12345/username</a>)</li>
  </ol>

<p>There's a <a href="http://meta.stackexchange.com/questions/131846/report-sites-that-use-stack-exchange-content-without-following-attribution-rules?answertab=oldest#tab-top">question where you can report this site</a> at SO Meta. Please add a new answer to it.</p>
