I have been a member on the Australian RSVP site for a very long tome. There are no checks on members, from my experience, it is full of scammers from Russia, Ukraine, Nigeria & the Phillpinnes.
On top of this the way the RSVP site works is that you pay for a 'stamp' to make message contact with the lady that your interested in. The first 'kiss' (no message) is free.
It is well known that RSVP fills its site with beautiful girls that are interested in receiving your paid message.
