I like this a lot even though my primary reason is unexpected subscription renewal. I started a membership site and tried to use every single thing I would want as a customer. One of the things was a reminder that my yearly membership was about to expire, and by doing nothing this would indeed happen. No automatic renewal (but keeping the account in an inactive state). Confident customers can renew for 3 years with a discount, but nothing will automatically renew. Turns out, customers love this attitude and happily renew when it's time.
