@AlexanderGruber Why did you let yourself get suckered in to
undeleting likely the most highly downvoted question on MSE? We know that BD ("Number")'s vote had to precede six months ago; I don't see any justification for undeleting a question with such a low score. Perhaps you'd like to explain and justify why a moderator, of all users, would undelete a post with net score of -73: a resounding rejection of the post by the community.
