"as far as I know the automatic recycling service does not work."
We are working to bring FREE recycles, then we'll see..

I understand that users like you (with many active RRs) will disagree, the problem is that few users (including you) have all the active RRs, so for a new user is almost impossible to find good RRs. You can still make profits but good RRs will shuffle between users after few months, we could be doing this under the hood but we disagree with this kind of practices. We do not rent bots or things like that. 
A rented referral should not be permanent because is rented, is not direct referral, we find RRs being extended even 50 times (4+ years), you can extend one RRs only the numbers showing on membership page, you can bypass one extension by buying premium RRs, and extensions resets after RR is recycled. You may see extensions like a contract. After contract is done RR goes to another user.

Logic is very simple, you CANNOT extend referrals where is showing negative value of extensions left.
