Field Validation

I need help understanding if this plugin will work for our purposes. We have a Permit Application Form. we have a list of past permit holders that are not allowed to purchase permits any longer – a banned list of poachers. Is it possible to use this validation plugin for a first and last name field, that would NOT allow a specific first/last name set to be submitted? Example: end-user types in John Smith, but John Smith is on the banned list, and the validation error comes back stating that John Smith is not allowed to apply and to call the office for further information.
