Remove word from $spamwords list

Hello

We have a client who’s business is Debt Review.

We have used your Visual Form Builder plugin to create a few forms for the client to gather data from their clients.

Some of the clients are getting the following error message:
Your responses look too much like spam and could not be sent at this time.

Looking at https://github.com/mmuro/Visual-Form-Builder/blob/master/includes/email.php
one of the $spamwords is Debt.

Is there a way we can remove this word for this client in particular?
