There was the the promises of huge/easy money. The urgency to get in early. The hype men that appeared from nowhere. The webinar that ended up asking for a lot of money. The promise of a product with essentially no details because it didn't actually exist (admittedly). And the fact that the guy didn't even understand how the blockchain/Steemit worked.
Add to that his history - convicted criminal (from his hedge fund scam with his company Hardcastle Hedge Fund), multiple other complaints about MLM practices and scams (such as WUKAR/Dubli) - and his overall behavior in general that is certainly nothing new, based on previous complaints and his own videos, and there is a pretty clear picture of who this guy is. Also, the fact that he teamed up with another person who is an alleged scammer adds to that picture.
Sounds pretty conclusive to me... Shame I missed the drama
