I really wonder how many colleges and universities deny a person admission or expel them if they participate in making porn movies or pose nude for Hustler (blaaah)! I have serve on college admissions committees and there is no question that asks do you do porn?
I have no idea if Christian colleges ask about porn per se, but they certainly will expel a student for porn. My alma mater would expel a student for serving alcohol, but that was another era. I don’t believe they would do that today.
Probably because there's nothing illegal about an 18-year old making porn.
