I don't think that you could be subject to any type of legal action, provided your comments are factual. Obviously slanderous comments regarding a shipper/carrier/broker could land you in some "hot water",if the aggrieved party thought it was worth the trouble to proceed with litigation. I think that we all agree, any postings on this site should be as truthful and accurate as possible. Stating that ABC Company has not paid an invoice that's over 100 days old is factual. Stating that ABC Company are cheats, liars, criminals, fraud artists, engage in known criminal activity, etc, etc. might be pushing the envelope. I believe this site is best served by its members relaying their experiences in a rational, logical fashion, without letting their emotions get the better of them.
