Hello,
I have checked your posting and here are my queries to give you accurate quote:
- Do you have defined rules or criteria based on which app has to identify the email or user as a fraud one?
- On identifying user as a fraud, what it should identify, what further steps to take? Only avoid registration with such user?
- Also would you have 3rd Party server to host app a Shopify does not allow hosting app on their server?
We are Authorized Shopify Partner and our resources have experience of developing custom Shopify apps.
Regards,
