Make sure the hot girl messaging you isn't doing research of her own:

I was considering joining after being a guest member for a couple of weeks and a collect email came.  I decided to check their Terms and Conditions and they basically admit to everything charged on your page.  I was suspicious that a hot girl would have her picture on her profile, and it turned out she was a scorned wife trying to catch her husband doing the deed. If it looks too good to be true, it probably is!
