take this punt as a graphic explanation of why you need to check previous reviews before seeing a girl.
Prior to this one, she had ten previous UKP reviews - not one positive.
In addition if you look at her AW feedback there's a high proportion of "feedback only" reports which give a very negative overview.
Both are enough to indicate something wrong with this girl, but add to that the pricing: £100/hr for a 35 year old British girl sounds very much like a "come-on" to a scam - or a poor service provider. It's very much at the low end of the price range, low enough to raise questions.
