I have many times seen a big rise and the WG become much harder to book. Who exactly is benefiting in this scenario is a big question as it can be viewed different ways of course.
The WG obviously benefits and punters unaware of her good service offered benefit, but does the punter originally giving her the review or feedback. With EE WGs a bit of publicity often means they are more likely to stick around for a while whereas if they had none they might leave or go elsewhere so a punter making her known to others is also hopefully benefitting himself.
The other point is this whole scenario mainly only affects Indies, a well known Parlour like HOD gets masses of great feedback but apart from their recent £10 an hour price rise which was the first for a long time the WGs dont get more expensive to see, although they certainly can get harder to book.
Ultimately its a question of how a punter views things, does he put his self interest first or decide to publicize the WG, completely up to the punter. Of course if you know other punters you can spread the word without publicizing if you wish to. There is no right or wrong to this in my view but if all punters put total self interest first the Positives Reviews board might be short of Indies.
After the punter has paid his readies and had his service then he owes the girl nothing.
The problem with sexual services is that the supply (for any individual girl) is limited and it should be her goal to maximise her earnings.
She has to strike the right balance with the price/ service and of course this is directly affected by the competition.
A simple way to do it is to build up a bank of regulars and give them the service they want at the original agreed price and then as her reviews improve then she can turn the gas up to the level to what the market will bear to new clients and then bring them into her loyalty scheme
She should say to the regulars that as long as you see me twice a month then the price will be £60 H/R but my usual is £75. She then has guaranteed income from her regulars every single month.
The problem is that pro$$ies aren't in general good business women and that's why they are WGs.
Regarding the reviews I don't see what's in it for the punter, it's all downside as far as I can see which is why I don't do FRs. But I'll give rec's privately to those guys who contribute to our forum and I have done so.
