This is because the Faucet asks its users to do so... and for doing so... throws some more peanuts at them.

Nothing wrong with this per se - if the business model is sustainable. But this is the big question mark.

I for example was a reader of this forum for about 4 months... and I just started posting when using this Faucet, too... I think I never posted on any other thread.

Okay. I think buying random referrals is not worth it. It is just like gambling.

I invested 150k and bought 5 referrals. The most active one claims twice per day and once per weekend day. So about 1800 satoshi per week. Two referrals claim not even once per day. The other two are inactive...

All good again for me. Beside my referrals bringing in 0 commission.

I just invested 60k satoshi into Referrals. But of course - each referral has to claim 600k satoshi to bring me back to break even... Good Luck.
