Sharing of your own volition is different from suggested sharing. I've always felt it detracts from the purity of the game and attracts the wrong sort of players. You could probably mask that by not advertising a reward and making it random or not affect gameplay, though. It doesn't feel good to make a game and wonder if the only reason anyone plays it is because you're exploiting their brain's propensity for gambling addiction.
