He was banned. Not sure why they let him back...
Basically the short version of the story is this. Goat made up several businesses to raise a ton of BTC from duped investors. Some of those businesses include a nonexistent arbitrage bot, a mining company that had no mining equipment, and a rice patty field in a 3rd world country (I missed a few but these were the most outrageous)... He then took all the raised BTC and dumped it into a ponzi scheme. He made a small fortune from this, and then when the ponzi collapsed, all of his businesses suddenly stopped and investors ate the loss. He then tried to stir up as much trouble as he could, to try and make it look like the exchange did something wrong. He is still trying to pin this blame on the exchange even after others were able to migrate with no issues whatsoever. No matter that he was selling investments that did not exist...
Falsely issuing securities of nonexistent companies to divert investor funds into a ponzi scheme for his own gain while leaving them all the risk. That is Goat.TL;DR
1. Raise Bitcoin from investors pretending to offer multiple safe investments.
2. Invest everything in the riskiest thing possible.
3. Keep all the dividends from risky investment.
4. When investment goes bad, say businesses fail and blame the exchange.
5. Buy a Bugatti
I'm just a bystander in all of this but I find it very suspicious that you would post such an obviously inaccurate post. Anyone who has been reading bct.org for a while can plainly see that the way you presented that is false.
One thing I'm not clear on, I'm assuming by the exchange you mean GLBSE right? Obviously if you're talking about GLBSE I think it's safe to say closing and down and taking everyones money is "doing something wrong".
And as far as him creating "fake business" he had posted pics of a room full of computers full of gpus so obviously there was some mining equipment.
The sharecropping idea if I remember correctly was after pirate's ponzi had imploded so you're claim of him taking all this money from other businesses and putting it in to pirate doesn't add up. And I don't specifically remember him taking any money for that yet anyway. And there's no reason to think it's necessarily a bad idea to invest in something like that. It's different that's for sure, and I'm not saying I'd be lining up to invest on that one, but nothing wrong with new ideas for btc investment.
He operated a pass through fund for the known ponzi. So yes people bought shares through him to participate in in Pirate's giant ponzi. Everyone who had any idea of what was going on knew it was a ponzi. At that point half the forum was gambling their money in the thing anyway, he had what, like 550,000 btc at one point?
So it really comes down to a moral question of whether or not you think it's right to allow people to gamble their own money in ponzi schemes. Theymos and goat obviously think people should be free to gamble their own money. I've never seen any evidence of goat actually scamming anyone but there have been constant accusations over the years. I don't have all the information though, so if someone come up with some real evidence I'd like to see it, but no one ever has as far as I can tell. Just more of the same vague, incorrect accusations.
