Nojiro : Fraud Filter, Blocker

In theory, this app is a great concept that is very useful to verify email addresses at sign up. However, there is an issue with existing customers who are already signed up for email subscriptions in your account, cannot sign up for a customer account. They receive a "this email is already taken" message at the sign up form with no way of creating a password to login. This makes the app impractical if you are importing your subscriber list and a customer wants to register their account. Reached out to support who is difficult to communicate with and has yet to fix the problem. If the app gets updated to resolve the issue I would recommend.
