Who's Liable When a Sponsored Post Breaks Disclosure Rules?

Every creator has asked some version of this after posting a sponsored video: if this was wrong, does anything happen to me, or is it the brand's problem?

The honest answer has three parts, and only the first one is about regulators.

Part one: the FTC can go after either of you

The Endorsement Guides put the primary obligation on advertisers, and the FTC says so directly: if enforcement becomes necessary, "our focus usually will be on advertisers or their ad agencies and public relations firms." Brands have the money, the campaign, and the ability to set rules for everyone in it, so that's where enforcement concentrates. Agencies are in scope for the same reason. If an agency runs the program, briefs the creators, and approves the content, it participated in the conduct.

The same passage names the exception, and it's worth reading closely: "action against an individual endorser might be appropriate in certain circumstances, for example, if the endorser hasn't made required disclosures despite warnings." Being told once and continuing is the fact pattern that moves a creator from unlikely target to plausible one.

That isn't hypothetical. The record on individuals runs roughly like this:

• April 2017: more than 90 letters to influencers and marketers, the first time FTC staff had written to influencers directly.
• September 2017: 21 warning letters to influencers who'd been contacted earlier that year, plus the agency's first-ever complaint against individual influencers. Two CSGO Lotto owners settled charges that they promoted a gambling site they secretly owned, and paid other influencers to promote it without requiring disclosure. The order binds them going forward.
• November 2023: warning letters to 12 registered dieticians and health influencers, and to two trade associations that hired them, over inadequate disclosure on aspartame and sugar posts.

"Warning letter" also stopped meaning "no consequences." Through the Notice of Penalty Offenses mechanism, a recipient who then engages in the flagged conduct can face civil penalties, which run to tens of thousands of dollars per violation and are indexed annually. The letters are the setup for the penalty, not a substitute for it.

The practical read for a creator: a first-time disclosure mistake is very unlikely to draw a regulator, ignoring a warning is a different situation, and every letter that goes out is published with your name on it. For a brand: you are the default target, and the fact that a creator ad-libbed something you never approved is not much of a defense.

Part two: the contract may put the cost on you anyway

This is the part creators skip and it matters more than part one.

Most brand agreements include an indemnity clause. Stripped of the language, it says: if your content causes the brand a loss, you cover it. The regulator may never contact you, and the brand's costs can still land in your inbox.

Look for these before you sign:

• Indemnity. Whether it's mutual, and whether it's capped. An uncapped personal indemnity on a $2,000 deal is a bad trade at any odds.
• Compliance warranties. You're often promising that your content complies with all applicable laws. That's a promise you can only keep if the brief tells you what compliant means.
• Approval doesn't equal a release. Some contracts say the brand's approval doesn't relieve you of your warranties. So they reviewed it, they approved it, and you're still the one who promised it was compliant.
• Takedown and correction duties. Who pays for a re-shoot, and on what deadline.

The clause worth asking for is the one that says the brand is responsible for the accuracy of claims it supplied. If they wrote the talking point, they should stand behind it. That's a reasonable ask and plenty of brands agree to it.

Part three: the exposure nobody signs for

Regulatory action is the least likely consequence of a bad disclosure. The likely ones are quieter.

A creator who gets caught with an undisclosed partnership takes a hit to the only thing they actually sell, which is their audience's trust. It doesn't come with a letter. It shows up as a comment section that changes tone and a brand that doesn't rebook.

A brand gets a version of the same thing, plus something worse: a competitor, a journalist, or a rival's agency can report a post to the platform or the regulator at no cost. Platform enforcement is faster than anything else in this article. A post can be removed or a Shop account restricted without anyone reaching a legal question.

What each side should actually do

None of this is complicated, and it splits cleanly.

If you're a creator:

• Disclose properly on every cut, including the ones edited down from a master. This is the whole ballgame and the first-cut checklist covers what reviewers look for.
• Don't make claims that weren't given to you, even ones you believe. This is the other place individual liability actually attaches: the Guides say a non-expert endorser can be liable for unsubstantiated statements about how a product performs, specifically when what they say goes beyond their own experience or wasn't approved by the advertiser. An ad-lib is exactly that.
• Keep the brief, the approval, and the contract for each deal. If a question ever arrives, the useful answer is "here is what I was told to say and here is who approved it."
• If a brand ever asks you to drop or bury the disclosure, that request doesn't move the obligation off you. Here's how to answer each version of it without losing the relationship.
• Treat gifted product as a connection too. Free product carries the same obligation as a paid post.

If you're a brand or agency:

• Put the disclosure requirement in the contract, in specific words, not "comply with FTC guidelines."
• Review the content before it goes live, and keep a record of the decision and who made it. A documented review process is evidence of a reasonable program.
• Monitor after publication. The obligation doesn't end at approval, and content gets edited, cropped, reposted, and boosted after you last saw it.
• Include your seeding list, not just your paid roster.

The through-line is the same on both sides: the party who can prove what was required and what was checked is in a considerably better position than the party relying on memory. The rules themselves are in the FTC disclosure checklist, and they're not the hard part. Consistently applying them across every creator and every cut is.

Why speed is a compliance issue

There's an uncomfortable connection between review turnaround and exposure. Creators post on momentum, and a cut stuck in review for five days sometimes goes up unapproved, or goes up on a deadline with the notes half-addressed. That's a compliance failure produced by a queue, not by anyone's judgment, and we put numbers on the creator side of it in what slow brand review costs creators.

A review that returns in minutes doesn't just make people happier. It removes the incentive to skip it.
