I think adding the option to assign a value of "0" would be a good idea for informational purposes. It would be good for when you want to report something suspicious but not increase points against a user.
Example:
A client provided a fake phone number (000-000-0000), we discussed this with them and they contend that they do not own a phone. We do not want to ding them with any points if they do not really own a phone (unlikely, but possible).
