Are you sure the account is banned or maybe locked?
No passwords or email change from the begging so I don't see it as hacked account.
Dont worry i have an actual staked address in the address staking thread too, i sent an email already, and yeah its banned it said so when i logged in, and it was hacked by the looks of it, someone posted malware with my account
