I can't add bank card as soon as I joined the PayPal and account was limited.

Here is the message I got. May I know what is the exact cause of error and how can I fix that?

PayPal does review accounts regularly, and any concerns with security, violations of the User Agreement or Acceptable Use Agreement, compliance obligations, etc., could lead to a permanent restriction. Additional information beyond what would have been provided to you in a notification and/or email would not be available due also to security concerns and due to such information being proprietary....in other words they do not give you an exact reason, they just direct you to the user agreement or acceptable use policy. I guess having a reason wouldn't make any difference if they have permanently banned you.
