Mate, you didnt get the content. It was a "wallet" for me. Nothing else. ETH, XMR and maybe in the past (2-3 years ago) some BTC and LTC.
I was already verified with all my data.
And of course I was able to verify me again with my passport plus picture of mine (not working).
With my ID-Card (scanned or as photo) and of course back and front.
And I am not doing such stuff or verifications the first time.
What they did is and was an illegal action.
They are leaving the U.S. market, what I already wrote down as information, on 1st November.
Whatever you are not seeing - at the end they did actions far over the normal ways!
After revoking manually all the new identification tries, and it was manually like you can proof by the timestamps - now it is still pending over 24 hours.
On monday 2 letters will be send by courier and the fun will start. They did it by purpose, I have the proofs and it is not because any KYC rules are touched or a problem.
And now they will pay for it a lot of bucks

This is not a story. It is a warning about what could happen with Poloniex.
At least, that they are not the right company to deal with your coins. Trust down.
