The reason this scam works so well is because at the beginning, the fees will still be low, new investors will be getting paid and the contract will seem like it's working... but as soon as people start investing large amounts the fee variable goes higher and it becomes painfully obvious where all of the money is going.
If the fee becomes too large the fee gets skipped as you saw in the transaction above. The next payment will go right back to sending all of the money to the owner.
This ensures stupid people stay confused.
By the time anyone has figured it out, newbie has already exchanged all of the ETH and is off to the next scam.
It's the wild west of digital currency. Be careful out there.
And here is the proof that both of these transactions FAILED:
