There are many reasons why an online casino like Bet365 would have your account blocked. Some of those reasons are too many failed login attempts, using a payment method that is not trusted, not supplying adequate verification documents, or creating multiple accounts, among other reasons. However, to know specifically why your account is blocked, you will need to find a way to reach out to them and get answers. You could be doing something that you didn’t even know wasn’t allowed. So speak to the operator and get answers.
