If you triggered AutoPay Enable, then, if a RR clicks an ad , the AutoPay value will be deducted from your purchase balance and 1 extra day will be added to the remaining days of that RR.With this option you will pay your referral with a discount of 10% in 30 days.
If you find your RR is a little lazy or do not want to work, so you have the option to replace the old RR with a new one.
To recyle one RR for standard or golden is $0.07. As seen on Upgrade section.
Autopay is $0.006 if you have RR from 0 to 250. As seen on FAQ.
