What I will says is that £50 an hour in Barking and Dagenham area is not uncommon. The normal rate is £60 an hour but on some occasion they lower their price for £50 an hour.
What is suspicious here is that she has PGs bit no phone number. But she is not going to make money for only 1 picture in PGs as people are not interested in paying just to see one picture. Moreover it is just 50p.
So this could probably explained as Steve said,
I will say it might be real you will meet a WGS but as you can not see her face she could claim whoever she is, so it could be "bait and switch" ....
So, do you think Dorothy is the real deal for £50 an hour? or another FAKE?
