To me, questions about locating hard to find material should be on topic for the site.
Answers as to how to find such material should not give directions as to how to obtain grey or black market copies of such material.
Where can I find a copy of "The Dragon, Issue 1"
Would be (probably, I'm only guessing it's hard to find) on topic.
Answers should fall into categories, like: "occasionally available on sites like ebay", "in PDF form on the (insert real CDROM here) that was released with (insert product here)", "for free on the WotC website if you purchase a DDI subscription (I wish...)"
And answers should not include: "here's a megaupload link", "in this torrent" ect...
I would say that updating the FAQ item about what kind of questions not to ask indicating that questions download links to pirated IP don't belong here, would be fine, if we were getting such questions on a regular enough basis.
And so to answer the question, given that we don't get many such questions, and given that there is (in the question that prompted this discussion) some evidence that the original poster believed that the material in question may have been free to distribute, I don't see the need for a FAQ update.
