I tried to create an account but the email address I tried to use was blocked; why?
Email providers or domains can sometimes be blocked if they are found to be exploited for abusive purposes.
This is often done with email providers who specialize in temporary or disposable email addresses. Often spammers or other troublesome individuals use these addresses for account creation and cause enough of a problem for the entire email provider to be blocked.
If you were attempting to use a temporary or disposable address to create your account then please switch to an address from a more reputable email provider.
