I've seen a couple of times now, questions being voted to be closed because the voters do no believe there to be a 'life hack' solution to the question.
A recent example is here - How to determine if US paper money is genuine?
It seems silly to me that just because one person (two so far in this case) thinks that there aren't any hacky solutions to the question so it should be closed.
As we can see from the attached question I have posted an answer which would appear to me 'hacky' therefore invalidating the vote to close reasons as well as all comments stating that it's not possible or whatever.
So my point is... Even though there is a reason to close of "Does not seem to need a life hack", surely there should be a period before someone should vote to close for this reason as one single person isn't going to know all the life hacks under the sun.
In any case, if it genuinely doesn't have a hack answer, surely an answer to the question explaining that and giving reasons as to why it doesn't have a life-hack solution, such as in this question: How to clean Blu Tack?. I just feel that it would make the site more usable for others looking for solutions, they will easily be able to see that there aren't any solutions and why there aren't.
