Basically there's pretty much no scrutiny or comeback for a shady profile on AW - VS is for girls who are too shady for even that minimal level of control.
I've only seen about 2 VS girls. If they are local what does it matter if they are B&S, you go and see who is behind the door and you have a perfect excuse to walk if you don't like. I'm always happy to drive 5 mins and take the risk it's a wasted journey. The 2 times I tried I liked what I saw.
Services available. well that's a risk. The first one I went to the girl agreed OWO on the phone, in the room and then mid punt refused. I asked for my money back (1st time every) and she went and found another (very sexy) girl who was ok with OWO. I guess we worry about Sergei but they are probably more worried about hassle in a foreign country.
2nd girl was really hot and seemed like she would be fun, but I was so shocked I didn't walk I went and booked 15 mins and didn't really get much out of it. I think it's worth the risk of going back but she's extra for everything.
Oh and yeah, the standard Romanian level of service is always an issue but that's not a VS thing. My suggestion is go see what's on offer if it's close, and if you like what you see negotiate hard on services.
