There are several possible reasons why your account has been banned:
1. Multiple accounts creating attempts will lead to your account being banned. One user only has one account each.
You may have to delete your other accounts and keep only one account you wish to continue using.
2. The account that has been detected violating any fraudulent or abusive behaviors will be banned.
3. Your account can be banned because you showed no sign of logging in bitcastle for a long time.
Whatever the case may happen, if your account gets banned, we encourage you to immediately contact our Support Team via "Contact Us" function.
