Nefario has proven himself to be ridiculously incompetent, so it might be safer for people who received extra BTC to hold it until Nefario distributes all of the BTC he has and he releases the share info.
So would we be right in assuming that no-one's going to authorise any salary payments to Nefario until this mess has been cleaned up and that the business will use its own remaining funds to top-up any shortfall if Nefario is unable to recover all the over-payments?
Yes. I never paid Nefario, and there's no way I'm going to pay him as long as BitcoinGlobal is in debt to users. And the remaining operating funds will be used to cover any debt to users. If most people who received extra BTC are honest and Nefario didn't spend any of the user funds (on lawyers or whatever), I think there should be enough money.
