I've seen many Romanian girls charge ridiculous despite of their beauty and body. Girls who charge 150-300/hr don't make big different with those charge 70-100/hr.
IMO even for porn actress should not charge more than 150-200/hr, although it's their rights to rate whatever they want, but what they can provide is way below the expectation, the probably most valuable service they can provide is the title of porn star/actress.
Sorry about your experience, wish you can have better punting next time.
