I'd guess those four profiles are just one Romanian girl (maybe two) trying to multiply their chances of business. One profile may be real, the rest fakes
All have the same pricing profile, all blonde, all bareback. They're stolen photos pretending to resemble the real girl
Probably one girl and a pimp "boyfriend". Seen quite a lot of those. Most of them are in some kind of exploitation scenario. I'd also guess she's in a hotel or serviced flat for just a few days
