Not working with user restrictions module

Hi,

I think this module does not check the rules which are set in the User restrictions -modules settings.

How to reproduce the problem:

1. Install User restrcions -module: drupal.org/project/user_restrictions
2. Create a rule, select Access type: Denied
3. Select rule type: email
4. add to mask field: "info@example.com"
5. Save rule

Try to register a new user account and put to email field "info@example.com", user is not possible to register.
But if you register a new user with "log in with Facebook" (simple fb connect), and a user which Facebook account has email address "info@example.com" is able to register.

I don't have any idea is this fixable in this module or should it be fixed in the User Restriction module...
