It's neither the providers or the hobbyists - it's the system, the admins. They've changed the grading criteria. It's impossible for me to get a 10 in performance because I don't do Greek or Gangbangs.
I've had a couple clients tell me they had to go back and forth with admins because they would not allow a higher score on performance. One review that I received could only go up to a 7 because the guy didn't know the hobbyist lingo and didn't include the acts we actually did in our session.
Here's what the actual guidelines say on the matter:
"An escort provider is only eligible to earn up to a 7, unless she is willing to perform one or some of the following during a session: Kisses With Tongue, Bare-Back Blow Job, Really Bi, and Anal Sex. For each of these services that are offered, her potential max score is raised by one point, with 10 as an absolute maximum.
If your review rates a provider higher than her maximum score, the score will be adjusted down to her maximum. "
Luckily my self-esteem isn't tied to my ratings so I don't really care one way or another. But how does anyone really determine if someone is 'Really Bi'? That sounds like discrimination, no?
