In all seriousness, what's the problem with this. I'm not a pornstar or involved in the porn industry, but do you feel working a job such as this shows bad judgment or some other disqualifying attribute? I'll bet you didn't know this, but there are a ton of female pilots and doctors who put themselves through school working at bars doing exotic dancing. Where do you draw the line? It almost sounds as though the applicant was proud of his/her accomplishment putting it out there so candidly.
Maybe "Adult Film Industry" would have been better than "Ex Porn Star" possibly, is that where you were going?
