Just had a look at the page and realised that it's almost 99% no Indians.

As an Indian guy born in AU. This kinda sucks that a bunch of immigrants ruined such a good thing.

In any case, I have an idea.
Allow indians that get VIP Ginza cards to build 'up' to qualify for women.

IE. There is a small subset of Ginza girls that don't have non-indian.

If you are indian you HAVE to go with them. If the punt goes well, with no complaints, you build 'reputation'..

This then unlocks other women.

I think this is a fair system that both protects women from a race of horrifyingly bad people, while also maximizing profits and 'letting the good ones through', and building customer loyalty.
