From my limited experience talking to people working in this space, the violence / human trafficking portion is not really a problem in the adult entertainment space. At least, many models definitely work voluntarily. I think trafficking is more of a potential issue at the shady ends of prostitution.
The downside of the adult entertainment industry is that you did hear of tales of questionable employers... it's less "violence" and more environments and/or tactics that sometimes seemed shady or unethical. There was also tales of drugs, sure. Also the pay is often relatively lousy. IMHO your best bet to avoid shady places is to support models / producers / etc. at an individual level, which is more possible these days thanks to the Internet.
(To be honest the industry it reminded me of the most is the music industry. Which has similar bits of shady employers / work environments here and there, similar drug issues, similar lousy pay, and a similar scenario where the best way to avoid the shady parts is directly supporting the non-shady artists and venues as much as possible.)
