If you're concerned, I would recommend that you stay with the licensed MPs. I've been to Muse and Perla so far. Every attendant I met seemed to want to be there. They were friendly and kind and I wasn't a client.
Bro, why don't you get it? You just don't know what is happening behind the scene in these peoples lives and by just looking at them you can never get to know their situation and circumstance for prostituting and they will never tell you about their situation... Because no man wants to hear about a women's unfortunate situation! Unless you get really close to them and actually hang out only then they might let you know some things... and only in that time...
