Spreading false info & trying to down someone's reputation is also called a crime

Yes, spreading false information with the intention of damaging someone's reputation is generally considered defamation and can be considered a civil or criminal offense, depending on the laws of the country or state in which it occurs. Defamation can take the form of spoken statements (slander) or written statements (libel) and can be damaging to a person's personal or professional life. It's important to be mindful of the information we share about others and to ensure that it is accurate and truthful. If you are the victim of defamation, you may be able to take legal action against the person responsible.
