The line between a legitimate complaint and an insult that can give rise to liability is not always obvious to someone running a business. Negative reviews, social media comments, and complaints on consumer platforms are part of everyday business life, but there is a point at which a statement stops being the exercise of an opinion and becomes a civil wrong, or even a crime against honor.

The Border Between Opinion and Insult

Brazil’s Constitution guarantees freedom of expression and prohibits anonymity, while also protecting the honor, image, and reputation of individuals and companies. These two values are in constant tension. When a consumer posts that a product arrived defective, that service was slow, or that they felt deceived, they are exercising a right that the Consumer Protection Code itself guarantees.

The problem arises when a statement leaves the ground of real experience and moves into attributing false facts. Claiming that a company “knowingly sells expired products,” with no proof at all, or accusing it of a crime it did not commit, goes beyond criticism and enters the territory of liability.

Brazilian law recognizes three relevant criminal offenses. Calúnia (criminal slander) means falsely accusing someone of committing a crime. Difamação (defamation) means attributing to someone a fact that damages their reputation, even if the fact is not a crime. Injúria (insult) attacks a person’s dignity or decorum through name-calling and general abuse. None of these is the same as simply giving a service an unfavorable review.

The deciding factor is usually intent. Good-faith criticism, even harsh criticism, is the regular exercise of a right and removes the unlawfulness. A statement driven by a deliberate purpose to humiliate, lie, or destroy someone else’s image, however, loses constitutional protection and exposes its author to civil and criminal consequences.

When You Can Ask for Content to Be Removed

A business owner who comes across an offensive comment usually wants, above all, to take it down. The path is narrower than many people expect. Brazil’s Marco Civil da Internet (the Internet Civil Framework) sets out, as a general rule, that a platform is civilly liable for third-party content only if it fails to take the content down after a specific court order that clearly identifies the material.

This means that in most cases removal depends on a court decision. The company must show that the content is false, offensive, or unlawful, and not merely unfavorable. True negative comments, even when they hurt sales, are unlikely to be removed, because truthful criticism is part of the right to inform and to be informed.

There are important exceptions. Content involving nudity or intimate scenes shared without consent can be the subject of a direct out-of-court notice to the provider. Case law has also been moving toward expanding platforms’ duties when faced with obvious unlawful content, but the core principle remains: a legitimate negative opinion cannot be removed just because the person criticized wants it gone.

Before going to court, it is wise to gather evidence. Screenshots showing the date, web address, and profile identification, along with a record of the concrete impact on the business, support both a removal request and any claim for compensation for moral damages, which case law also recognizes in favor of legal entities.

Brazil’s Constitution guarantees freedom of expression and prohibits anonymity, while also protecting the honor, image, and reputation of individuals and companies.

Right of Reply and Retraction

Another tool often mentioned is the right of reply. It has specific rules for offenses published through mass media, with a short deadline to exercise it and proportionality to the harm done. When applied to news articles, it allows the person harmed to present their version in the same space and with the same prominence as the original publication.

In the world of consumer reviews, however, the tool has limited reach. A single comment on a review platform is not the same as a news report, and what usually exists is the option for the company to respond publicly to the consumer and clarify the facts. A well-written, courteous response almost always does more for your reputation than any court measure.

When there is a serious and proven insult, the right course tends to be demanding a retraction, with or without a claim for compensation. A voluntary retraction, by the way, works as a mitigating factor for the person who made the offense, which is why many disputes end without a lawsuit.

Choosing between responding, negotiating, or litigating should take into account the reputational cost of each option. Reacting aggressively to an isolated criticism often turns a forgettable episode into a public controversy, with more impact than the original statement.

The Risks of Suing a Consumer

Filing a lawsuit against someone who posted a truthful opinion is a decision that calls for extra caution. If the consumer simply reported something that actually happened, the case is likely to fail, because the truth of the account and the absence of intent to offend rule out liability. The practical result is additional exposure for the business, now associated with the image of a company that tries to silence unhappy customers.

There is also the risk that the move will be read as an attempt at intimidation. Lawsuits brought for the sole purpose of silencing legitimate criticism can be seen as an abuse of the right to sue, exposing the plaintiff to a ruling for bad-faith litigation and to a compensation claim in favor of the very consumer who was sued.

There is also the amplification effect. A complaint that would have reached only a few people gains visibility once it becomes a lawsuit, draws attention from the press and the online community, and ties the brand to a posture of persecution. In that scenario, the damage to your reputation far exceeds the harm caused by the original comment.

Litigation is justified only in the face of a clear wrong, such as false accusations of a crime, deliberate lies, or coordinated campaigns of disparagement. In those cases, proof of falsity and of intent is essential. Outside those situations, investing in customer service, in a thoughtful public response, and in resolving the complaint out of court offers a more reliable return than a fight in the courts.

Entrepreneurs who treat criticism as an opportunity to improve, and reserve the courts for genuine insults, better protect both their reputation and their assets. The yardstick is always the same: the truth of the facts, the form of the statement, and the intent of the person speaking.

Frequently Asked Questions

Can a negative review be removed just because it hurts sales?

No. True criticism, even when unfavorable, is part of the right to inform and of the consumer’s right to share their experience. As a rule, removal requires a court order recognizing that the content is false, offensive, or unlawful, and mere commercial harm is not enough to justify it.

When does a comment stop being opinion and become a crime against honor?

A statement goes beyond opinion when it attributes a false and offensive fact, accuses someone of a crime that never happened, or hurls insults for the purpose of humiliating. The central test is the intent to offend combined with the falsity of what is claimed. Good-faith criticism, even severe, remains protected as the regular exercise of a right.

Is it worth suing a customer who made a truthful complaint?

Generally, no. If the account matches reality, the lawsuit is likely to fail and may also expose the company to accusations of trying to intimidate consumers, with the risk of a ruling for abuse of the right to sue. A courteous public response and an out-of-court resolution of the complaint usually do more to protect the business’s reputation.
