The situation doesn’t warrant that. There is still a better than even chance those NSR can be withdrawn later, I would estimate.
My guess is that it is not Poloniex’s specific intent to defraud or harm NSR depositors. Rather, they have grown around 10 fold (just a guess) in 2017 and are really struggling to meet the increased demand for services and support. NSR does not impact current listings and trades, while only involving a modest quantity of customers. Therefore, I speculate Poloniex has chosen to deprioritize its NSR support. If true, the suggestion is once they get acclimated to operating on the scale they need to, they can begin to diminish the list of unresolved issues.
For these reasons, I suspect the best course of action is for affected users to keep expressing an interest in NSR withdrawals to Poloniex, and to keep asking Poloniex when withdrawals will be enabled.
At some time in the future, we can still investigate the possibility of some civil proceeding brought by one or more of the NSR holders.
If at some point it became clear that there was not a reason to expect NSR withdrawals to be enabled in the future, and that a civil lawsuit could not be used to correct the situation, a socialization, or spreading, of the losses among all shareholders might be considered. It would need to approved by shareholders. I think any such discussion is premature.
It is worth remembering we may want to be relisted on Poloniex in the future. We don’t want a reputation of being difficult to do business with.
Still, the situation is unfair and understandably frustrating for those like you, @Bubleek, who have NSR deposits at Poloniex. I wish that weren’t the case.
