I could be wrong but I'm pretty sure you can set your rate to whatever the hell you want. Obviously you're not going to "work" as much the higher your rate is. But it would seemingly weed out the obvious. I highly doubt anyone who has a high rate is soley doing just that unless they have consistent long term clients. It's common sense.

I have no interest in feeling awkward alone with a random guy. I'm awkward and weird enough as it is already. But I'd be charging a shit ton of money too if I were Gracie or any other high price tag girl. Because why the fuck not!
