US Advertising Transparency

A black box
with 300 million
people inside.

In the United States, an online ad can promote almost anything, reach millions of people, and vanish the moment it stops running. Nobody keeps a copy. If it sold you a fake product or a fake story, there is no way to prove it ever existed.

The problem

What's hiding in the black box?

Whatever someone pays to put there. Gone in hours.

Because nothing is archived, none of it can be checked after the fact. Every kind of campaign below has run at scale in the US, and each one would have left no trace at all if someone hadn't gone digging.

Toxic counterfeit products
Lead-painted toys, fake car seats, counterfeit medicine, advertised to parents for a weekend and then gone. If your child gets hurt, you can't even show anyone the ad that sold you the product.
Documented
In May 2026 the US Consumer Product Safety Commission launched a crackdown on counterfeit safety labels and fake certification marks used to push dangerous, mostly foreign-made products into US homes through e-commerce. CPSC
Dangerous health fraud
Fake cancer treatments, unlicensed weight-loss drugs and bogus supplements, aimed at people who are sick and searching for help. The ad runs for a day, reaches a million people, and is gone before any doctor or regulator hears about it.
Documented
In July 2025 the FTC charged telemedicine firm NextMed over deceptive pricing, fake reviews and misleading claims used to market online Ozempic/Wegovy-style weight-loss programs. FTC
Foreign influence operations
State-backed operations don't need to hack anything. They buy ads, point them at swing states, and let the platform handle delivery. Once the election is over, there is nothing left for researchers to study.
Documented
Russia's Internet Research Agency bought 3,519 Facebook ads seen by 11.4M Americans in 2016. They are public only because Congress force-released them. In 2024, DOJ seized 32 domains in the AI-ad-driven "Doppelganger" operation. House Intel DOJ
Financial scams
Crypto pump-and-dumps, fake investment platforms dressed up as banks, phishing aimed at seniors. By the time the first victims report it, the campaign is over and the evidence went with it.
Documented
Australia's ACCC sued Meta over celebrity crypto-scam ads. Researchers who counted them found 63 advertisers, 150,000+ ads, $49M spent, countable only because they ran as political ads. Deepfake ads impersonating Martin Lewis stayed live "for only two days." ACCC TTP
Predatory gambling
Unlicensed gambling apps pitched to minors and to people trying to quit. No age checks, no oversight, and once the campaign ends, no evidence it was ever shown to anyone.
Documented
In 2026 the UK Gambling Commission found illegal, unlicensed gambling ads in Meta's own ad library and told Meta: "If we can find them, then so can Meta." The library is what made the crime visible. Gambling Commission
Dark political ads
Disinformation built for the last 72 hours before a vote. It only has to survive until election day. After that the library is empty and there is nothing left to correct, retract or punish.
The tell
Meta already keeps political and social-issue ads for 7 years, so archiving is clearly not a technical problem. For commercial ads it simply chooses not to, and they vanish the moment they stop running. Knight Institute

Anatomy of a ghost campaign

24 hours, a million people,
and then nothing.

This is how one plays out on Meta in the US, hour by hour.

Hour 0 · Ad goes live

The ad starts running.

An advertiser launches a campaign. It might be counterfeit baby products, fake medicine or foreign propaganda. While it runs it does appear in Meta's Ad Library, but only if you happen to be looking for it at that exact moment.

Hours 1-24 · Mass delivery

It reaches exactly who it was aimed at.

Meta's targeting delivers the ad to its chosen audience: parents, seniors, teenagers, voters in one particular state. It might reach 50,000 people or 5 million. Nobody outside Meta will ever know which.

⚡ Potential reach: 1,000,000+ people

Hour 24 · Campaign ends

The damage is done.

By now products have been sold, money has moved, and whatever story the ad was telling has been read and believed.

Hour 25 · Total erasure

The ad never existed.

It drops out of the Ad Library and nothing is saved: not the ad itself, not how many people saw it, not who it was aimed at. A journalist can't find it. A parent can't show anyone the ad that sold them the toy. A regulator has nothing to act on. It is as if it never happened.

Content: erased Reach: erased Targeting: erased

records remain after a non-political ad ends in the US, no matter how many people it reached or how dangerous the product it promoted.

On the record

The times we found out anyway.

Every case below is documented by a regulator, a court, a congressional committee or a named investigation. They have one thing in common: the public knows about them because someone fought the evidence into the open, not because the ad system kept a record.

11.4MAmericans reached

Russia's 2016 election ads, recovered only by subpoena

The Internet Research Agency bought 3,519 Facebook ads seen by 11.4 million Americans. They became public only when the House Intelligence Committee force-released them in 2018. Earlier, after a researcher showed Facebook had under-reported their reach, Facebook deleted the cached ad data researchers had been using and called it fixing a bug.

$49Mon scam ads

63 scam advertisers and 150,000+ ads, visible only by accident

The Tech Transparency Project documented 63 scam advertisers running more than 150,000 ads for $49 million on Meta. Researchers could count them for one reason only: the ads were classified as political, so they sat in the archive. Identical commercial scam ads leave no trace at all.

2 daysthen gone

Deepfake "Martin Lewis" crypto ads: live for 48 hours, then gone

Consumer group Which? found Facebook ads using a deepfaked video of Martin Lewis and a fake BBC page to push a crypto scam. The ads were live "for only two days" before disappearing: long enough to reach victims, short enough to leave no public record. Australia's ACCC has sued Meta over the same kind of celebrity scam ads.

32domains seized

"Doppelganger": an AI-powered ad operation, caught by the DOJ

In September 2024 the US Justice Department seized 32 internet domains used by a Russian operation that ran AI-generated paid social-media ads to push propaganda at US voters. What the platforms disclosed was voluntary; the record exists because prosecutors built it.

~$16BMeta projection

The scale of the problem, by Meta's own math

A 2025 Reuters investigation reported that Meta internally projected roughly 10% of its 2024 revenue, about $16 billion, would come from scam and fraud ads. Almost none of those commercial ads are archived anywhere the public can see them.

The whole argument, in one row

The same scam ad runs in both places. Only one of them keeps a record.

🇺🇸 United States

The ad runs, reaches a few million people, and ends. It is removed from the ad library and nothing about it is kept: not the content, not the reach, not who paid. Anyone who tries to trace it later, whether a journalist, a regulator or a parent who got scammed, hits a dead end.

🇪🇺 European Union

The identical ad is archived for a full year under Article 39 of the DSA, with its content, who paid, how it was targeted, and how many people saw it in each country, searchable by anyone. That data trail is what let regulators fine X €120M and rule TikTok's ad repository non-compliant.

The gap

Same platforms. Different rules.

The EU's Digital Services Act mandates transparency. The US has no equivalent.

TV advertising has always been public.

Every TV commercial airs in the open, where anyone can see it, question it, and complain about it. An online ad can be aimed at millions of individually selected people, and in the US it runs and disappears in the dark. There is no good reason for that.

In the US, anyone can put any message in front of ten million people. When the campaign ends it vanishes, and there is no trace of what it said, who saw it, or that it ever ran at all.
