FWIW, it looks to me like they're selectively locking the other thread when they're not at the computer and can't be vigilantly deleting messages. Kinda crazy.
While it makes for good fun watching them try and rationalize their fraud why are you guys wasting your time arguing with them. You should start a collection to hire a private investigator to get to the bottom of what is really going on. I mean they had to think the price of BTC would either be stable or increase over time otherwise their whole business would have been sunk. I'd be willing to bet this whole charade is just them trying to keep what is now $100 Million+ in BTC they collected.
