I’ve never seen an MMO where offending players are rewarded. While those who have done nothing, receive rewards that do not even reach the feet of those who have taken advantage of some bug.
Yes, IMC, you have moved beyond the limits of the acceptable. Give rewards to players that take advantage of bugs? Are you doing this so you do not lose the players? Because it is having the opposite effect, because many will abandon the game because of this stupid act.
