Yup. If the bonuses are attainable at the stakes you play and perpetually refilled, then you can count this as an alternative to rake. I don't play at PokerStars, but my understanding is this is pretty much how people work their frequent player point system. You just gotta figure out the math to see what you're really taking home... I used to play UB w/ no rakeback (not that you can't get it... I couldn't get it...) ... it was profitable until they changed their bonus payout to make it d@mn near impossible to earn.
