Yes the method mentioned is quite popular at party poker. i discussed the same with my manager, trying to see if i could get more than their standard $75 CPA. He basically said, send the players, if they are good, we can discuss a higher CPA. I never bothered trying it, not worth $25 a player.
But if you tell the program what you’re doing and they accept it, there isn’t anything wrong with doing that from the affiliate/program point of view.
