Ok so I made accounts in those "chinese cam sites" and they are indeed all fake. These play recorded video clips on fake user interface and fake chat for 15 seconds then asking to pay in order to continue. If you clean cookie and reload preview page you cab re-play the fake thing all the times.
It is not even a same fake site with affiliates or white labels linking to it... each webmaster installs the php script and flash animation on its own (it must be leaked or free) and just write own details on the where to pay page
