# frozen_string_literal: true

# Some users in our db are both unconfirmed AND have no outstanding confirmation_token
# This is true for those users due to the following:
#   - We haven't always used Devise's :confirmable module (it generates a confirmation_token when a user is created)
#   - We have set `confirmed_at` and `confirmation_token` to nil via Rake tasks (lib/tasks/email_confirmation.rake)
# This concern is meant to streamline the confirmation process for those users
