I actually see this as how users can creatively use a site for what they really want to use it for despite how it is designed. These people wanted to vent their complaints and have other people see them. Since they were complaining about really small businesses, few people would ever really see them unless they searched for that specific business (that is how the site is designed.) So by crowding all of their complaints on the BBB listing they can maximize how many people see their complaints. If Yahoo really cared about this product they could come up with some creative ways to get the user's entering their comments in the correct place by also providing an outlet for them to have their complaints be more visible. In a sense all of these random comments are complaints against the BBB because the BBB makes it so hard to complain online (or doesn't provide a better way to do it.)
