One of my recent answers got deleted while it got scoring of +12/-2 and for some time it was the accepted answer. I would consider this scoring to be rather positive. The answer that got deleted provided a different perspective then the rest of answers (and, let it be, it could be viewed as slightly off-topic). I admit: there were things to correct (and those were corrected) and there could be areas to improve the answer, however there were no suggestions of any kind to improve the answer - it just disappeared. Sorry, but I don't get it.
What is the policy here? I know the general policy, but this case seems odd for me. Especially that the general policy is to "rather edit and improve then delete".
I don't want to argue: "please undelete it!", that is not my point. Yes, I spend some time on writing it, so I did not like the idea that it was deleted. However, I am mostly interested in knowing what is the policy, because situations like this rather discourage to writing further answers.
Link to the deleted answer: Are all simulation methods some form of Monte Carlo?
The answer came back from the dead.
