I happen to know the parties involved in this dispute and it was a comment of a personal nature NOT a professional one. The person leaving the comment is bitter and angry that they are unable to run their own business properly and have consequently lost business to the person they are trying to ruin via this network. I have previously done business with both of these people and can testify as to which is the more professional, hardworking, and courteous one. If you are a responsible and professional business owner, there should be no need to slander anyone just to try and get ahead. Let your work speak for itself as both of these parties have. And don't be angry with anyone other than yourself when your work speaks poorly for your company.
