Endorsements, Influencers, and the Law of Paid Praise
By Casey Scott McKay ·
Paid praise is now a multibillion-dollar advertising channel governed by a body of law most of the people using it have never read. This article explains the architecture: Section 5 of the FTC Act supplies the prohibition, the Endorsement Guides at 16 C.F.R. Part 255 supply the interpretation, and the 2024 Rule on the Use of Consumer Reviews and Testimonials at 16 C.F.R. Part 465 supplies something the Guides never had - civil penalties. It defines what counts as an endorsement, what counts as a material connection (much less than people assume), and what "clear and conspicuous" actually requires after the 2023 revisions. It maps liability across the three parties who can be charged: the advertiser, the endorser, and the intermediary agency or network. It explains why the Supreme Court's AMG Capital decision reshaped FTC strategy toward rulemaking and Notices of Penalty Offenses. It then covers the private claims that follow a public enforcement action, including Lanham Act false endorsement, right of publicity, and consumer class actions, and closes with the special regimes for children, health products, financial promotions, and AI-generated endorsers.
