I have recently chosen to not leave a prossie feedback on AW (despite her trying to force me to) simply because I don't want her to retaliate maliciously. What I would never do us leave her positive on AW at the expense of other punters. I have negged her here.
I agree with Adam's reasoning and like you, believe that the public disclosure of PM chats is out of order. I do however, question the OPs motive for disclosing such info?
The only way one could be totally honest on AW and avoid a spiteful negative in return, is to disable the account afterwards for one month. And who would do that, without employing multiple accounts?
Rebecca had a reputation for telling giant porkie pies on this forum and it's right to take somebody to task over that. However, it's also fair to point out that she isn't here to defend herself with this review. A bit overpriced for me, considering the multitude of options in London but by all accounts she is a decent SP and is pretty enough, in my opinion. Perhaps better to judge the girl on her service and general attitude towards punters, rather than test her memory about hospital appointments!
