We've all seen posted answers that aren't relevant to the question. There has been wide discussion about not voting to delete incorrect answers, enough to the point where text has been added to say "[close] flags should not be used to indicate incorrect answers." What should we do about answers like this one* which is probably correct on the user's modded Minecraft server but not helpful to the general Minecraft playerbase.
The answer is indubitably low quality as it is both short (23 words long), and has spelling errors. But what should be done? It could be rescued with an edit that corrects the spelling and better indicates that mods could be used as a solution, but it could also be deleted because of it's current quality.
Is it worth the effort to rescue a question that isn't helpful to most players, should it be closed and make it not our problem, or should I just downvote and move on?
