If you regularly earn & redeem your CR Points, you have nothing to worry about.
Members must earn at least 1 "revenue" point within a 6 month period to keep their points active. A revenue point is any point earned on CreationsRewards, except for: Daily Trivia, Promo Codes, Referral Points, and any bonus points.
If you fail to earn at least 1 revenue point, your points will be null and voided after 6 months. It's very easy to earn points on CreationsRewards, and this activity requirement is not hard to meet.
If you fail to redeem your CR Points after 2 years, they will also expire on a rolling basis.
