The document summarizes a defamation case between Biomatrix, a medical company, and Raymond Costanzo, Ehpraim Morris, and Richard Costanzo, who posted over 16,000 critical messages about Biomatrix on an online forum under pseudonyms. The posts made unsubstantiated claims about Biomatrix's products and management and caused the company's stock price to drop. Biomatrix sued for defamation and the court ordered the identities of the posters to be revealed, finding them guilty of libel.
