Well, I'll have to take your word on that I guess but the fact is this glitch that rewards already unlocked achievements may have rewarded you for achievements you unlocked through SAM in the past.
So you are not completely innocent in all this like you seem to think.
Yes, I have used SAM on some achievements in the past, like some buggy Walking Dead achievements.
But should I seriously be stoned for what I did in the past? I did not exactly have a time machine to see that the Playfire Rewards were developed.
