He needs to define "most". Otherwise "most" is entirely subjective and he can drag this out forever with no good reason. It seems highly unlikely that anyone who hasn't already returned their overpayment will suddenly do so. Whether "most" is 70%, 80% or 90%, Nefario needs to be clear about what the benchmark is and how long he intends to wait for it to be reached. Right now, the way it looks from the outside is that he's setting it at an unrealistically high level so that he can use it as an excuse for halting refunds and continuing to with-hold information from asset issuers and their users. It's up to Nefario to convince people that's not the case.
What is Nefario's plan if his totally arbitrary benchmark for "most" is never reached? He needs to commit to a date after which the refund process will continue whether or not that benchmark has been reached even if it means that users receive less than the full amount owed to them. He also needs to pass on user information to asset issuers right now there is literally no good reason for his continued failure to do that - he's intentionally created a situation where the value of that information is diminishing by the day.
Nefario is not acting in good faith. Sooner or later his frustrated users will start acting in bad faith too and he'll have only himself to blame when that happens.
I have read his blogentry the way that he went through half of the lists of users that got a double payment. So i think he is contacting them one by one and forcing them, maybe with their asset infos or naming them on the board or something like that. In a week he went through half of the list and i think in another week the rest should be done. Whatever the result will be then. I dont mind if he make the users public that keep others users money hostage. I mean thats no better than nefario keeping the asset infos hostage. These users have no right to complain. Whoever they still are.
He should of course be specific... but on the other hand... he cant be too specific because the users with double payment could think... "oh then he doesnt need my money back" or similar.
At least he doesnt claim that he expect to get everything back. And it looks like he is working on this topic at the moment. So in one week lets see what he is saying. If he is naming the users keeping the others users money hostage or whatever new infos he has.
