You can explain this to czech police who investigates against cc on a regular base because of girls accusing cc of tricking them. Till now their releases seemed to be waterproof as these girls sign everything without reading or even understanding what is written there.
What they offer to the girls? Empty promises as pretending to be an agency who can give them many well paid jobs. Promises of private bg scenes which than get published against their will... so from your logic this is good biz behaviour?
Some of the girls there are already professionals who are listed at some other agencies and booked from there as you realized right and thats fine. But many of these never seen before beauties come from here:
http://www.netlookmodels.com/It is strange that most of them never make the way to a real agency and therefore dont work with other productions. Now how to trace them if only netlook has their contacts, na smartass? So it is not even worth to create threads with cc girls and ask for more scenes as there simply will not be any outside of that network and the professional girls already have their threads.
