Is there anyone who verified successfully after using fake data at registration? And did you have to do some "special" verification process because of the fake data?
You might get verified because poloniex ownership has been changed few months ago and like @magneto mentioned they are using third party verification netverify which is same as used by other payment processors like skrill and neteller which will basically checks whether your entered name (at the time of verification matches with your name and other details in your uploaded document.
But you can't hide your identity for the shake of anonymity if you are willing to use poloniex like centralized exchange.
