<p>Our active statistican <code>kjetil b halvorsen</code> is consistently modifying old questions by adding/removing tags. This <a href="https://stats.stackexchange.com/questions/253853/joint-correlation-in-r">closed</a> question is an example. The bumped questions is making me harder to navigate the recent problems. Consequently, it's contributing the <a href="https://stats.meta.stackexchange.com/questions/5325/we-have-a-very-large-widening-gap-between-questions-and-answers-how-do-we-fix">widen gap between questions and answers</a>.</p>

<p>May I ask the point of bumping the old and closed question?</p>
