I think it's just a preference as with everything else such as OWO (which is equally risky).
People make too much of it. We can offer whatever we want and will attract the clients that want those services.
I mean, what's the mindset of someone who wants to be an adult baby for example? (That would risk my patience!)
As a service provider, I decide on the risks I want to take and advertise accordingly.
The biggest risk for me is what type of person is going to walk through my door, which I why I screen like MI5.
