Criminal Intimidation, Insult, Annoyance and Defamation
(1) Making/publishing (by words, signs, or visible representation) an imputation about someone, intending or knowing likely to harm their reputation, is "defamation" - covering imputations about the deceased, companies/associations, and ironic/alternative-phrased statements. Harm means lowering someone's moral/intellectual/professional/caste standing, credit, or implying a disgraceful physical state. Ten specific exceptions protect: true statements for the public good; good-faith opinions on public servants' or public figures' conduct; true, substantially accurate court-proceeding reports; good-faith opinions on court-decided cases; good-faith opinions on public creative works; good-faith censure within a lawful authority relationship; good-faith complaints to someone with lawful authority over the accused; good-faith imputations made to protect one's own or others' interests or the public good; and good-faith cautions given for someone's protection or the public good. (2)-(4) Punished with up to 2 years' simple imprisonment, fine, community service, or a combination; printing/engraving known-defamatory matter carries up to 2 years' simple imprisonment, fine, or both; selling such printed matter carries the same.
This is the core criminal-defamation provision, balanced by ten carefully defined exceptions that protect legitimate speech - truth for the public good, honest criticism of public figures and officials, fair reporting on court cases, honest reviews of public creative works, and good-faith complaints or warnings - all conditioned on genuine good faith, not a licence to make reckless accusations.
This section's ninth exception is directly relevant to scam-reporting itself: making a good-faith imputation about someone's dishonesty specifically to protect your own or others' interests (for example, warning others that a particular seller or scheme is fraudulent, based on a genuine, good-faith belief) falls within a recognised defamation exception - though the good faith requirement means reckless or malicious accusations still carry defamation risk.
