what i can say is that, this guy is a professional con man, he has never delivered anything to his customers, and got full money for all his empty promises.

Then, he created confusions among the members. For example, if he scammed one RM1000, he refunded him rm250, and gained some "feedback" saying that oh, shit, he refunded me rm250, but still, he still scammed rm750, and then for other cases, he would refund but not in full, then all the members became into two groups, one thinking he is a full conman, one thinking "what", he still refunded what?
