I am curious to know what this site's policy on identify-this-movie questions about pornographic films are. I have read the discussion at Are adult movies (as far as industry, actors, etc... are concerned) on topic?, but that question is 2+ years old now, and doesn't quite address this specific issue.
Note: by "pornographic films", I don't just mean "films that have a sex scene" or "films that are rated NC-17" or even "that stuff that airs on Cinemax late at night" - I mean straight-up 18 USC § 2257 pornography that exists for the sole purpose of titillation.
The reason I'm asking is that we're starting to get a trickle of these over at Anime.SE (here's the latest example [stack.imgur mirror] - the question itself is clean, but there is porn linked from the question), and I'm interested to know what communities elsewhere on SE think about these questions.
(Update: here is the corresponding discussion on Anime.SE; for reasons beyond my ken, the consensus there appears to be in favor of pornography-identification questions.)
