Don,
There is a definitely gaming done by the agencies. Certainly, as you can see by reading on this board, they are sending out admiration letters simply because you fit some basic criteria defined by the woman. I would hazard a guess that eight out of ten times, the woman does not see your profile until you send an EMF in reply.
Now, does this mean you should stop? What are your goals? Are you truly committed to finding the woman you love halfway across the world? If you are like the rest of us, you are ready to spend some credits to find that one special person.
