Yes, what Anika said, I'm afraid.
You're not the first, and sadly you won't be the last. Argh, argh, argh.
It does indeed happen with models. In fact, one of the Spanish bunch of scammers' other sidelines is a site pretending to be an agency to get your pet into films and other modelling work!?
Because (human) modelling is less taboo than even the 'non-sexual escorting' some of the scams pretend to be involved with, there's actually some movement in clamping down on them.
Oh, I see the latest version of the scam is to say 'We're legit, look we only charge a commission on actual work found. Oh, except for the first one, when we'd like half up front, just to prove we can trust you...' Of course that first booking is faked, but the fifty quids add up.
