a porn actress? How would one find out if someone made a 'blue' movie in the past?

[maximuslseneca]

I know this girl of whom I have strong reason to believe made one of those 'barely legal' porn movies a couple of years ago.I wont go into detail-to protect the 'considered-innocent' She's now 23 and I do know her full real name but dont know her 'Porn name'. How would I go about finding out if she had done this?Oh BTW Goog search doesnt help unless I have more info-like the movie name or someones 'Porn name' And no Im not going to ask her straight out for reasons I wont state here..
How would you know its none of my business?Maybe I gave her a diamond ring fercrissakes
