I have seen a few of these babes change names and then a couple weeks later the prices are up. But I have to tell you that most of them that do this are worth it. They know they are worth more so that is why it is done. Actually I dont blame them, they go through a lot of bullshit at times with some guys and these babes really earn their money. Not everyone is as nice as me or you.  Good luck. Treat them all well. It is a rough business.
