If she's just curious, then why put "Sex workers are allowed to charge whatever they want" at the end of the thread? Apparently by "sex workers", she's referring to herself, which means she can charge whatever she feels like, so naturally I followed that lead and saw that she charges $400 an hour, then she starts a thread "Is meeting a sex worker an activity reserved for rich people?", again the sex worker is OP herself, so the question basically becomes "Is meeting her for $400 an activity reserved for rich people", why does she ask? Maybe she's not getting enough bookings from average joes, and business is slow, that's why she has time to start this thread ask these obvious questions, which is basically a survey to feel out potential clients.
I'm just making a logical deduction.
