At the moment, ReferralCandy is only able to assist with 1 tier referral programs.
You can reward the original advocate for their direct referral to a friend, but won't be able to reward the original advocate when their friend refers someone else.
For example, if A refers B, and then B refers C:
A will be rewarded for referring B
B will be rewarded for referring C
A will NOT be rewarded when B refers C
