It also depends on the section of the country as to the safeness of BackPage. In my area, it's not highly thought of. I usually tell guys that ask, 'you can look anywhere, but if the one you are hot for does not have reviews SOMEWHERE, move on'. I look in lots of places for potential providers to visit, and when I find one that piques my interest, I go searching for reviews. It's what we guys refer to as 'research', similar to providers' screening of clients. It's just as important for us to stay safe as it is for providers.
IMHO, you might have gotten more answers posting on the General Discussion board than here.
