I work in London regularly. There used to be lots of profiles on we-chat advertising massage and sex. Tin eye showed them all to be fake pictures. Spent many a bored hour in my hotel room winding them up. All advertised the same 3 post codes and rates of £150.00 ph.
They have just about all disappeared now as I think the site has clamped down on spam profiles.
I do have a couple from, past, good, shared FBSM experiences, that I keep in touch with. By-pass the organ grinder and cash straight to the girl.
