If you gave your referral link to someone and they receive an error when signing up, then it could be due to one of the following reasons:
1) They are from the same household as you. We only allow one account per household.
2) They have been previously blocked from our website.
3) They already have an account on PrizeRebel.
4) They are from a blocked country such as Russia or China where we see significant amounts of fraud users.
