Yesterday, I asked a question pertaining to the origin of a quote from MGS2. The question can be found here (Edit: The question has been removed since it is off-topic). Now the reason it is downvoted is due to some questionable cross-site posting on my part, which is my bad, but not the reason I'm asking this Meta question.
In the comments, it was mentioned that "sourcing is not really in our (Arqade's) area of expertise". I accept this, but if it really isn't, shouldn't there be an area in the FAQ that includes this as being outside our area of expertise?
I would think it'd be covered under Game Identification, but wouldn't the quote count as an audiovisual artifact? Or is a quote of text not enough? And if not from that rule, is there another rule that states that this sort of question isn't covered by Arqade?
Related to, but not a duplicate, of this.
