Traci Lords was underage when she made all but her final film (which she owned).
The Girls Gone Wild producer has escaped child porn charges since a judge ruled that those tapes are not pornography (although he still employed a minor who was too young to legally sign a release). He was also facing charges of being a drug dealer but I don't know where that stands today.
Larry Flynt contracted a murder hit against Bob Guccione.
If you were put in charge of guarding prisoners in the War on Porn, you'd likely be looking after some wiseguys. Maybe some 4-eyed geeks too (the kind who created SPAM, autodialers, spyware, and popup-hell code).
Nasty stuff happens when you force an industry to be underground. BTW, Traci Lords used fake ID, and the child porn guy likely was just not being as careful as he should have been. I doubt either included a conscious effort to use a minor in porn, except on the part of the girls.
