I firmly believe that is question is off-topic. Starting with this argument:
There are 25 open questions whose title start with "what is" and only six closed ones.
Irrelevant to back up your template from questions from 2011. There are questions from 2011 that are pure theoretical research and some with no notable claim. However, we're in 2015 and new standards have been enforced.
Our GOLDEN question rule is that:
Questions must be about a notable claim
Furthermore, this question:
What is the original source of "Everything in the world is about sex, except sex. Sex is about power."?
is dissimilar to this one:
What is the source for the supposed "sound of hell"?
The quote question can be reformed as "Did Oscar Wilde say this quote?" since is notable claim attributing the quote question to Oscar Wilde.
An answer to this question would be finding the source of the quote.
The hell question has a notable claim saying that the hell story is true, be the hell story has been already debunked on skeptics.
An answer to this question would be finding out if it is true or false or unanswerable. Not necessarily finding out the source of those sounds.
This question "What is the source for the supposed "sound of hell"?" already links to another question that shows that the "alleged hell story" is false, but yet the OP is curious to know the source of those sounds.
To give you example on how this sounds. It is like me asking this question:
Question: Who is behind the twitter account that predicted the World Cup results?
Question Body: Hello skeptics, I know the story is false "Did the Twitter account Fifndhs predict the exact World Cup results ahead of time?" but I would like to know who is the owner and person behind this twitter account. Although, we know the story is false, there are 25 questions that start with "who is" and are on-topic so please keep my question open.
PS: Please ignore the "notable claim" rule.
