Almost certainly. Any legit site will close your account when they discover that you violated their terms of service. You probably will not be able to withdraw your funds.
I am not suggesting that you violate their TOS again (by creating a second account), but your only option would be to create a new legitimate account and starting from scratch there. I would be very careful when it comes to trying to move any money from the old account to the new one, as it could cause you to lose access to both.
Hopefully, you didn't have a lot of money invested in the old account.
