Re the Mona Lisa Models link above...
Something rather fishy about parts of that one... They have an escort in the "ultimate" section for 3,000-6,000, and the name listed is Melissa Foxx. However, if you go to the page
http://www.monalisamodels.com.au/home2.html
And take a look at Melissa Foxx, you'll see that the pic given on the page is the exact same pic that the model Nicole Neumann has on several sites such as the one below

In particularly this one...

And now compare...

From looking closely, I'd say that the Melissa Foxx pics, even though somewhat blurred, look like a model other than Nicole Neumann. Makes you wonder what else is unethical there...
