US Advertising Transparency
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.
What's hiding in the black box?
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.
Anatomy of a ghost campaign
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+ peopleHour 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: erasedOn the record
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.
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.
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.
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.
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.
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 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.
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
The EU's Digital Services Act mandates transparency. The US has no equivalent.
Platform by platform
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.Explore the platform transparency data →
