No secret that the pics are fake, there were threads years ago where some of the agencies tried to explain. Since we know why and we know that the girl is likely to be somewhat in the ballpark we go and see and bail if this is not the case. Fake pics never kept me from seeing asian hotties and having a great time. The trick is finding which ads are doing it but still providing quality talent.
There are the rare ads with real pics like Korean Sara and Asian Violet (indy). If you truly have yellow fever then use your best common sense and go try one. Leave if she is not acceptable and try the next one. Not really that much different then non-asian ads these days, more fakes then real. The asians have just been doing it longer, and yes they are successful. Most of their business does not come from review boards like Terb.
