First off, there's a Terms of Service.
It rather clearly states - no porn.
You cannot ask questions about which actress is in which porno, or the name of a porno, etc. No one is going to research that for you here.
I have no idea why the site is at the top of search engine rankings for that, but understand that people do ask questions about cheating if their spouses are watching a lot of porn. Those topics are often tagged as porn which may be why Google is incorrectly picking this up.
