GLBSE is strong-arming Goat into accepting their terms or making his investors suffer. This means that GLBSE is directly causing investors to suffer. Who invests at a place like that? It's a scummy move for sure.
I hope GLBSE will realize that their petty silliness is going to massively harm their reputation and that they will do the right thing and fix this mess. Yes, Goat's conduct is questionable. But that doesn't even begin to excuse GLBSE's and/or Nefario's conduct. If GLBSE doesn't make Goat and their investors whole (or explain some angle to this story that I'm not aware of), I will consider GLBSE itself a scam.
Nefario made a promise, with the apparent authority to bind GLBSE, that he could not keep. Nefario or GLBSE should cover any losses that resulted from Goat's reasonable reliance on that promise. (He is not entitled to profit from the debacle.)
As for the disabling of Goat's account and delisting of his assets, I hope GLBSE can explain some justification for that action. And GLBSE has to find some way to make their customers whole. Goat is entirely within reason refusing to cooperate with the coerced and broken claim process. People who buy assets through GLBSE have a contract with GLBSE and should be able to rely on them.
I dislike Goat and I like Nefario and GLBSE, and I still can't see this their way. Arbitrary account disabling, especially in retaliation for speaking out against getting shafted, is totally unacceptable in my book. People have gotten scammer tags for "if you sue me you won't get your money back". This is way worse.
Goat has already made a massive profit off those shares. As for Nefario's actions, well he has to answer to the glbse shareholders. I can assure you - they arent happy
