Related: I've often been looking how to do X, find an SO question asking that, but the answerers there refused to answer until the person explained why they wanted to do X, and then all the answers (correctly) told the person that they actually needed to do Y and explained quite well how to do Y.
I actually need to do X, so those answers are useless to me.
Then I find another question on how to do X, and the mods close it as a duplicate of that earlier question. Even when the questioner specifically notes in their question that it is not a duplicate of that earlier question because they really need to do X the idiot moderators close it.
