WW, the problem here is OP has overly detailed the compromise the SP made to make up for a supposedly legit error. The spirit in which these two have engaged may well have been totally honourable but now that she has shown herself to be so accommodating she will be targetted. This is almost a certainty given our collective experiences of how SPs have seen the number of insistent punters change after reviews that made them popular, for whatever reason. Whilst we all wish for SPs who are consistent in performance and behaviour regardless of colour, creed, size, shape, looks, nationality of punter the services would always be YMMV subject to behaviour, hygiene and manners of the punter.
Whilst she can indeed turn "cunters" away there's nowt she can do about them fabricating reviews on whichever site to her detriment. Whilst she protects herself from entertaining them she is still victim to their retribution. Agreed there will hopefully be few of them but one's one too many. Dropping profile(s) and assuming new name(s) doesn't help as ordinary UKPers may well collectively find her again and connect her history...
Whilst UKP was specifically set up for punters to help other punters its all cummers welcome policy means it is repeatedly abused to abuse SPs.
I like your term 'cunters', it says it all for those who would abuse WGs, financially or otherwise

.
OK, I get your point about not mentioning the exact offer the WG made to make amends for the let-down of the first abortive punt. Having said that, had ADF
not mentioned the exact offer, I think we both know that at least one poster would have asked exactly what that offer was!

I think the fact of the matter is,
cunters gonna cunt. I don't think ADF's detailed review would make a non-cunter turn into a cunter. Guys are either a cunter or they're not.
As for cunters threatening to write a bad review on her unless they get a discount, if that were to happen on UKP then I think there's generally enough collective nous on here to be suspicious of such a review, bearing in mind who wrote it, his history on here, and the review history of the girl in question.
As for guys telling WGs they have accounts on UKP in the hope that they'll get a better service or even a discount, that clearly does other punters a disservice, in reality they're trying to get a better service for themselves not for others. It doesn't work for
Michelin Star restaurant reviewers, and it doesn't work in the world of punting either.
