Spreading false info & trying to down someone's reputation is also called a crime
Yes, spreading false information and attempting to damage someone's reputation can be considered a form of defamation, which is a legal offense in many countries. Defamation refers to the act of making a false statement about someone that harms their reputation or causes them to suffer damages.
There are two types of defamation: libel and slander. Libel refers to written or published false statements, while slander refers to spoken false statements. In either case, the statement must be false, and the person making the statement must know or should have known that it was false, and must have intended to cause harm to the person being defamed.
If someone has been defamed, they may be able to pursue legal action against the person responsible. This may involve filing a lawsuit and seeking damages for the harm caused by the false statements. However, defamation cases can be complex, and it can be difficult to prove that the statements made were false and intended to cause harm.
