Given the fact that they are airdropping tokens, it doesn't seem like they're even going to bother with sustaining the ponzi scheme by paying the first few investors. It's much more likely that they'll just pull an outright scam as soon as their ICO ends, because of the tokens that they're giving away for free.
Anyhow, ponzi schemes hidden in the form of crypto/tokens are nothing new. It's kind of a throwback to the days when lending coins were popular and the next big thing... Until every single one collapsed eventually and people were brought to their senses.
Could they be reported to mods for constantly creating new ANN threads, btw, or is that not against forum rules?
