This scenario could be somewhat possible, I guess:
Dude comes up with an interesting BTC faucet concept. He hopes that people love the idea (this worked out for him), invest, but never have enough time for ROI. That way, he'd be making a lot of profit. But wait, he wasn't trying too hard to convince people, therefore made the levels quite fantastic and worth the investment (for the user of course), most people made a lot of profit, started cashing out, and now his BTC wallet is empty, and he cannot possibly pay anyone. Because of that, he's hiding (in shame) from the investors.
if that were true why start a thread with "ponzi" in the title, in the "gambling" section, and then link to it from the website?
No I dont think it was a faucet concept that just got out of control, I think it was a ponzi and they always will blow up eventually. It takes an exponentially larger amount of money each iteration until either growth does not equal or exceed payouts or all the money in the world is deposited. In either case it collapses.
