- The lowest tier VIP level at pokerstars (that you can achieve from a few hands of poker play) amounts to 8.8% rakeback and more with stellar rewards, freerolls etc. It would be very hard to be a real money player and not achieve bronze star.
- You say stars "didn't pay dime" like pokerstars no longer exists. I can assure you they are still alive and well, and they are actually larger than 1 year ago despite the events of Black Friday.
The way most affiliates incentivize you to use their affiliate link is by giving you a cut of the revenue.
How did you think it worked? Full Tilt giving rake back direct to players just because they signed-up thru some 3rd party link? Why would they do that?
The reason why some people who sign-up can't get rakeback and are told that "their affiliate doesn't support rakeback" is that some affiliates chose to get paid a flat CPA fee of $75-100 rather than a lifetime percentage. This is also how PokerStars, etc, runs their programs.
but we are getting way off-topic. I was correcting the original comment above about what the definition of rakeback was.
Stars didn't pay a dime in rakeback unless you hit one of their VIP tiers via their point system. Vast majority of players, I'd guess, didn't qualify.
