The cease-and-desist letter gives you ten days. You wrote a review, or warned a customer, or told an unflattering truth about a former vendor in a way that cost him a sale, and now his lawyer calls it defamation. The letter demands that you retract the statement, take down the post, and apologize, or face a lawsuit seeking damages it sets in the six figures. It is printed on heavy letterhead and written to make you reach for the delete key before you reach for a lawyer. The threat is designed to make silence look like the cheapest path.
Before you take anything down, understand what Illinois law actually protects, because a great many of these letters demand the retraction of speech that no court could ever call defamatory. A defamation claim is far harder to win than the letter lets on, the First Amendment and the Illinois Constitution protect opinion and truth at the threshold, and Illinois has an anti-SLAPP statute, strengthened in 2025, that can turn a bullying lawsuit into a bill the sender has to pay. The letter is the opening move in a negotiation, not the verdict it pretends to be.
A defamation claim in Illinois, as the Supreme Court set out in Solaia Technology v. Specialty Publishing Company, requires a false statement of fact about the plaintiff, an unprivileged publication of that statement to someone else, and resulting damage. The words that decide most cases are “false” and “of fact.” Opinion is not defamation, truth is not defamation, and a statement the law treats as privileged is not defamation, no matter how much it stung.
