Referrals are when you tell a friend or family member about PassPorter Boards, they come and join us, and they type in YOUR member name during the registration process. That's a referral.
Infractions you do not need to worry about -- that is what we give people who spam our message boards with advertising and somehow I doubt they are concerned about earning points.
Let me know know what else you'd like to know and I'd be happy to explain.
