Raffi,
Not that it should matter but since you are so professional and brought it up......I'm probably older than you (38) and started
BikiniVoyeur in 1999.
Like I first stated, I'm a professional in my niche. That's why content that I shot is all over a couple of your tours and in your member sites. Because I know what I'm doing and am a professional.
As far as what reasons I think cause aff programs close? I would be speculating if I were to say for sure but i'd guess it all boils down to when they quit turning a profit. It doesen't happen all that often from what I see.
