Thank you, it worked beautifully. I'm guessing you can use a similar approach to checking for 'unique' emails/usernames by requiring the model in the validator class, using the value to search for existing emails/usernames in the database and if one is returned, to throw an error?
You can use a custom rule
See example from the docs:
