i believe that poloniex willfully violated its terms---they breached contract, which is a civil tort worth your deposited money + possibly additional damages. they have refused to pay creditors in spite of good faith compliance with their terms. if they make the argument that they were overwhelmed by customer verification queues or other such nonsense, i would counter that they were grossly negligent in complying with their own stated terms.
like i said, i believe that waiver of your right to sue would be laughed out of court.
the irony here though, is that you would need to identify yourself (to poloniex and the courts) in order to sue poloniex. if the ultimate issue is shielding your identity, you can't get resolution from the courts at all IMO.
Great conclusion. I didn't think about that and you're are absolutely right. No matter what path you choose, either they keep blocked your account (and your money) or you will be obligated to provide your data... This is a sad situation, badly managed. I don't know if the people are going to suit them (I don't have any money in Poloniex, so I won't take any action), but maybe public pressure can be a tool.
BTW no return call today so monday I goto my own states attorney general.
Let's see what happens, and best of luck.
actualize us if you can, please, this is a big issue and, under my point of view, how it is going to be seen and resolved matters a lot in the crypto world.
I hope you have your funds back soon.
