....................................Hey, I've got a great idea... don't offer a promotion and you won't get abused!
very bad idea! players like good and +EV promotions so why should they suffer because of promo abusers? every player should be glad to participate in a +EV promotion and no one should abuse it! easy as that
My view is that while playing games one's ethics should never be put to question. A game should be of sound structure as soon as it is available to be played. This +EV game (promotion) that was offered to the players was NOT of sound structure and was able to be exploited, so exploited it should be and the person offering it should face the consequences of his poor judgement.
I'm not opposed to a loss-leader strategy (get people in the door by offering something that is temporarily -EV for you) but if you let yourself get taken advantage of while doing so, that's your own fucking fault.
