This isn't the first time I have been messaged by an SP. It happened to me with one in Birmingham after I left her a neg.

However this is the first time it is regarding someone else's review. Since I got along with her very well I think she was comfortable messaging me.
There is the option to say she should join, and reply herself. It's an interesting discussion but I don't think a conclusion can be reached without the assistance of a mod or forum helper. I suspect the answer will be, don't bother posting the messages, however I would rather ask.
Firstly what are you doing telling escorts you are a member on here?

As far as posting on behalf of an escort who doesn't agree with a review and taking her side when you have no evidence apart from her word to show the review is wrong is unbelievable.
Did you bother to read the rules you agreed to when you signed up, I'll remind you just in case.
1 Site ethos/mission
This Forum puts the interests of Punters first through the sharing of Reviews. The Forum does not endorse or promote any service provider or any other site. This site is totally independent. No favouritism, no special treatment, no vested interests and
no pandering to service providers. Members are expected to post Reviews, although there is no formal quota (see rule 27). General chat relating to Punting is allowed on the appropriate Board.
2 Service Providers
This site allows service providers to be members, but zero tolerance for touting, flirting, attention-seeking and negative attitude toward punters. Service providers must respect the ethos of the site.
This site is neither a chat platform between clients and service providers nor a support site for service providers. All service providers / non-punters must reveal their working identities - no 'anonymous WGs'.
What are you trying to achieve, a freebie off the escort for being her knight in shining armour.
