Rented referrals performance gone down after 1 month?

what is it?
my RRs are active first month(avg=7 & 8)
after one month,they don't click more than 15 days(avg=4....)
i can't understand,more than 100 RRs are not active after 1 month.
what can i do?

none to answer my question

Are you try to Recycling RR?

If i start to recycle them,all RRs must recyle

Try to recycle RR down average 5, and try to recycle last click RR for max 7 days.

BETTER IDEA IS
to upgrade ultimate membership that only maintain my RRs profitable due to auto recycle.

golden membership - 12 days -auto recycle

diamond membership- 10 days-auto recycle

ultimate membership-7 days-auto recycle
