What do you think about this ?

What exactly is this? That doesn't sound like a good thing to me, could you explain more and what is a ptf?

Except the $1 to extend the referral (which is rather high compared to the original acquisition cost), this is pretty much the pricing at GagaBux. So far, my experiment with renting referrals at both GagaBux and NeoBux yield the same result. Your initial acquisitions are expected to be part of the bad batch of referrals. Why? The good ones are probably taken and those that get churned in the pool are mostly the inconsistent members plus a few good ones who joined in recently. In my opinion, if you want to catch those few good referrals, sorting out good referrals from the pool a few referrals at a time is not the best solution. I did it that way acquiring one referral at a time based on availability of funds. But statistically speaking, it is highly probable that I will fail to catch them. Anyway, I have neither the time or money to be picking referrals so I'm giving up on that idea.
