You can't be sure that the photos are genuine, just like on a dating website... Just sayin'.
My experience is that they are trying to get the P2F people in. There is no harm in making enquiries, and then make up your own mind on the merits or otherwise of the offer. I have chosen not to pursue any of their offers as they have expected me to lay out quite a lot of money up front which I deemed unnecessary in light of the rewards being offered later in the process. Caveat emptor I think.
