Yes, in certain extreme cases, legal action may be pursued against a reviewer—especially when the review is defamatory, false, or part of a smear campaign. However, legal processes are often expensive and time-consuming. Before going that route, businesses should document everything, attempt peaceful resolution, and report the review to Google for policy violations. Legal action may be a last resort when the reviewer refuses to take down the content and significant damage to reputation or revenue can be demonstrated. It’s wise to seek guidance from an attorney or work with an ORM firm experienced in handling such cases.
