When I had my talent agency, I would regularly approach people at the gym who fit what I was looking for. I never had any bad experiences, however my main focus was to acquire talent for a mainstream t.v. production that was adult themed, not right out adult modeling. I did scout for a few paysites in the past, but that was more of just having referral cards on hand at a gay club.

I think if you present yourself to people in the right way and come across as a professional, you can at the very least get an answer of "no thanks". In a sense I was pushing the envelope, as I started my agency at a young age and that combined with my "gym scouting" could have landed me in some trouble!
