One of the major dangers by misusing the "BCC" or blind carbon copy line in a business e-mail is that if I send an email out to six people, and blind carbon copy someone, then if someone on the "To" line hits the "reply to all" button, there is a chance with some companies that the "reply to all" will go to the "BCC" person. The two people don't know that anyone's been blind carbon copied because it's a blind carbon copy, so that can really cause some challenges depending on what that person may type within the business e-mail.
