<p>So I answered this question <a href="https://stats.stackexchange.com/questions/143578/jelly-donut-puzzle-what-can-statistics-say-about-these-donuts/">https://stats.stackexchange.com/questions/143578/jelly-donut-puzzle-what-can-statistics-say-about-these-donuts/</a> </p>

<p>My answer got downvoted but that is not the point. The point is that the question got -4 votes, and all answers got -1 or -2 votes. However, it is protected by moderator. I did not see anything wrong with the question, other than possibly it is ill-posed. I have never seen this situation before. Shouldn't question protection be used to avoid spam answers on very popular and useful questions? </p>
