GLBSE shut down as it was not regulated.. this time, it appears he is doing it properly.. so he may have learnt his lessons. atleast once he is making profits anyone that lost money in GLBSE can then get it back by sueing him personally, now that he has some money behind him and a reputation to protect in this new venture.
Nefario -- with malice of forethought -- shut GLBSE down in a manner
guaranteed to cause many or most of the exchange's users to lose money. He
deliberately chose to not send asset owner data to each and every asset issuer. He
deliberately chose not to allow asset holders, nor asset issuers access to even a snapshot of the final balances of their accounts.
I could go on (and on and on) as to how the shutdown was maximally bungled.
The bottom line is that he
deliberately chose to cause his users to lose $millions.
If that's the kind of person you wish to entrust with your funds, I have no response.
