Just letting you know that I just successfully made a wiithdrawal from bittrex, so I am not too sure what's going on there. When I was first asked to verify I sent them a ticket demanding that they do not make demands of me.. Perhaps that helped? I don't know for sure. But, it is worth a shot. It's your BTC after all, not theirs. I debunked their reasons for wanting my identity in the message, so if you do the same perhaps they will lift the ban.
