a lot of people are really angry about this situation. and you guys here saying "Oh no don't email Roman again, it might break him!"
I'm pretty pissed about this situation, too, but all I'm saying is, if Roman isn't talking, yelling at him or flooding him with e-mail won't prompt him to talk either. And if he has a lawyer
and he is protected by an LLC, then you likely won't get much with legal threats, either.
Actually, if you are concerned about him holding your USD, and you sue him, instead of getting your USD back, all the USD he holds might get divided between the USD he owes from the recent bank closing
and the BTC he still owes from the September hack. Since the BTC is a much bigger value, your USD portion may be tiny compared to what the BTC people get. (Disclosure: He owes me a lot of BTC, so this would actually be a better outcome for me).
So all I'm saying is, look at it from his point of view. If your business had its bank account closed, and you didn't feel like talking (I know you would keep people informed, as would I, but pretend you didn't want to or were advised not to), what would
your reaction be to e-mail complaints and/or threats? Would they motivate you to be more open? Hopefully, Roman is a professional business type, and can just ignore them instead of taking any of them personally.
