Something strange here: Perfectly centered break of a perfectly aligned pool ball rack
Searching for 'mathoverflow 156263', the number is the questions number, I find various links to the question. It seems this question just somehow became really popular way beyond the usual audience, yet there is nothing wrong about this; it already had really many views earlier. To wit, OP of q got the famous question badge already on February 3rd, so already then it had 10k+ views.
I only protected the question, since it attracted two non-answers by new users. Other than that I think there is nothing particular to be done about this (perhaps even protecting was not necessary). It might be (yet) another instance to show that this asssociation voting is not so good, but then at least in this case OP of answer made a lot of effort and provided good information so in some sense it is really a great answer.
More playfully, one could say MathOverflow has now its analogue of the Batman equation.
