wow, man, you took the words out of my mouth.
you can achieve this very easily without any referral system.

the referral system works this way:

if somebody signup free account after visiting any of your netload link and activate the affiiate program, so this somebody wants to be an uploader.

but you know what, netload doesn't give you anything this referral earns to you.

and your so called referral link in your account is pointless too,

even if you signup 2 netload accounts and refer each yourself, no matter how much you want, you won't get credit for what the other account earns.

so the referral system is dead actually, netload is just too damn lazy to remove that info.

and you have to understand how rebills works first:

like you said, if somebody has a lot of sales and he has a lot of old customers that trust him, he can simply stop uploading anything to the old accounts and just earn from rebills, once somebody buys premium with your link, you will get rebills every time he renews his account , he doesn't need to click on any link anymore.

even if he clicks new link from other uploaders and login the old account and renew, you will still get credit for the rebills.

so, the best way to keep old customers and also get new customers is to have 2 accounts: one with 60% rebills, the other with 90% plan or $12

and if you want to earn the most of this best way, it's to convince your old customers who trust you already to renew for 3-month or 6-month
and don't forget to try to convince your new cumstomers to signup for 3-month or 6-month account, though it's harder to do this with new customers.

the most difficult part is to confirm whether it is legitimate to have 2 uploader account with different affiliate plans, otherwise, it is really risky to have 2 uploader accounts.

@ amartin99
read this post,and you will know what kind of people want 2 different plans.
if netload offered 60%/60% or 50%/50% plan instead of 30%/30%, less people would need 2 accounts.
