This rating is about the accuracy of language advertisers list on their ads, or when you speak with them on the phone.
Some advertisers do not speak example, English, even tho they listed this language as good on their ads. Often an English-speaking friend answers the phone, messages, sms pretending to be the escort in question and once you arrived the escort that perform the services does not speak English well or at all.
Was the language information you got accurate and true?
