Legal agency or not, the profit is still there. Are more chances to be controlled and do work hours and/or towns/cities you do not want to with an illegal agency.
Lets not mention the advantage they can take if it is not way you can report to the police (well, the way is, but not the will).
Whats happening with the agency in Kerry. For many years they have Kerry under control. Illegal agency , escorts who do not work for them are sent the police to their door. If that was a legal one, easy to report them and I am sure I could go there and work in peace...
I have seen ads on Spanish sites, where escorts from Ireland are looking to bring girls from Spain, providing accommodation and doing the phone for them. A friend of mine contact one of this ladies, once in Dublin airport she rang this lady and was told she has no place for her... So, my friend booked an hotel for a few days until she found a proper agency to work with.
Nice story, is it not?! My point is this scam would be less if agencies would be legal and advertise as such.
The agency provides you accommodation, phone and you have the client at the door, for that they has to be payed. (Well, not you, as a native English you can manage yourself ) ...
You and I pay the accommodation, phone credit and sometimes go mad cause of some stupid ppl calling us. Nothing is free and is less stressful to not have to answer your own phone..
