Your account's security is our first priority, and Hibiki Run team is taking every measure carefully to protect it.
When this particular message pops up 'Your account is being investigated due to malicious activities.', it means our automated backend system has detected unusual and suspicious activities conducted in your account such as automated transactions, high failed attempts on login, etc. hence it is locked for further investigation to prevent potential damage to both you and others.
During a normal procedure, the account will be available after a thorough investigation is done within 24-48 hours. In case of higher delay, please report to our community manager.
