<p>Regarding your general feature request I agree with @Tim's answer: you can raise it on Meta.SE if you want but I think it  has zero chances of being implemented.</p>

<p>Regarding your specific example of my answer <a href="https://stats.stackexchange.com/a/90903">https://stats.stackexchange.com/a/90903</a> you are right to notice an important issue: the 1st version of my answer was entirely missing the point (it did not contain any false claims but it did not answer the question either). Nevertheless it got 12 upvotes. As I wrote <a href="https://stats.stackexchange.com/questions/90902/why-is-leave-one-out-cross-validation-loocv-variance-about-the-mean-estimate-f#comment308845_90903">in the comment from 2015</a>:</p>

  <p>@Jake, you are right, my answer (from over a year ago) does not make a lot of sense; I have already noticed it myself but forgot to deal with it. Funny that it got 12 upvotes :-/</p>

<p>Too bad! Lesson to learn here: answers that are missing the point can get many upvotes.</p>

<p>My advice: if you spot such a case, leave a comment and maybe even mention it in chat or on Meta, and perhaps other people will agree with you and help downvoting the answer. The original answerer, if they are still around, can then either delete the answer or fix it.</p>

<p><strong>This is exactly what happened in this case:</strong> back in 2015, motivated by comments and downvotes, I have fixed my answer, and now it gives exactly the same reasoning (right in the 1st paragraph under the disclaimer) as your answer here <a href="https://stats.stackexchange.com/a/357404">https://stats.stackexchange.com/a/357404</a>. So I'm not quite sure what's your problem with my answer <em>now</em> in 2018.</p>
