I just go on these basics, if the girl is very good looking with great body, ( too good to be true ) very low price, ( around 100 an hour , give or take ) has a private gallery, has no phone number and usually in somewhere like Barry, mountain ash ( granted this ones in Cardiff ) type town, no feedback. And generally disappear after a couple of days. obviously the odd one will pop up and be genuine , but Thay will hang around, answer e-mails and usually put there phone number up ( from the start ) as I say I just ignore, if there still around weeks later I will investigate, but 99 times out of 100, Thay are long gone.
