Few minutes ago I remembered that the old version of gptreasure had gold membership (I think it doesn't exist anymore?) and also, even though I realize this is not a PTC thus the system is much different than what I'm about to suggest, I always wondered "What about people who register to the website without being referred by anyone?"
So, the (bad?) idea is, what about a referral renting system mixed with memberships? Essentially, like PTCs.
Considering it has not been done already and it's not exactly something "original and unthinkable", I think there's a good reason why this is a bad idea, just thought that the unreffered people and the lack of ability of some people to refer people could provide more money both to the website (renting, extending, etc.) and the users by having good referrals.
All this could be accompanied by memberships (maybe to extend the limit of the maximum rentable referrals?) which could be bought or earnt or maybe both.
