I don’t really promote poker so I’ve no vested financial interest in the success or failure of affiliates promoting rakeback schemes. Having said that, I’m not sure what the issue is here.
Surely, competition is the cost of doing business. If one business wishes to undercut another then that is their prerogative. It is your choice as a competing business to follow suit or not. If you wish to compete with the rakeback sites, then you know what you need to do. If you don’t, then you have to find your own angle to bring in the players.
