Send Points to a Friend
MageRewards allows merchants to give their customers the option to send points to a friend. While this may work well with your loyalty strategy, it's important to note that the easiest way for customers to cheat a merchants' loyalty programs is to gain points by creating multiple customer accounts, then sending all of those points to one account. By enabling "Show Send Points to a Friend" some customers might be able to do this.
Example: A customer receives 500 points for each account created. The customer creates 100 accounts and sends all of the 5,000 points to one central account where they are able to get a product for free (using the 5,000 points).
