Address the Current Block (The Domain Issue)
Creating a new account with the same domain will not work because the domain itself is likely on a "blacklist" within the system due to the previous suspension.
Do not create more new accounts: This can trigger further automated red flags for "circumventing systems," which is much harder to fix than the original suspension.
Focus on the original account: You need to resolve the suspension on the first account you created. Even if the information is technically incorrect, it is the one associated with the domain's history in the eyes of their automated systems.
