<p>The question at <a href="https://stats.stackexchange.com/questions/5523/">https://stats.stackexchange.com/questions/5523/</a> , for example, was quickly closed as "pure advertising," which it is.  Nevertheless it still appears among the list of questions and thereby serves its intended purpose of spamming this community.  Thus closing appears to be an ineffective resolution.  What <em>effective</em> options do we have to counter such abuses?</p>
