The $962 Million Fake Influencer Problem: What Temu's Meta Ad Network Means for Creators and Brands

Temu spent up to $962 million on Meta partnership ads in the UK and EU over 16 months, and researchers say 73 of its top 100 "creators" were probably fake. That is the headline finding from Czech nonprofit Online Risk Labs (ORL), reported by Fortune on August 31, 2026.

The top account, "Ya Lili," had 183,000 Instagram followers and 129,000 on Facebook under a different name. Its AI-generated gadget videos were boosted by Temu and seen more than 1 billion times. Almost certainly, no such person exists.

Within days of the story, Temu pulled back. Of the top 100 accounts, 54 stopped running partnership ads almost immediately, and Temu's partnership ad volume nearly halved, per a Fortune follow-up on September 25.

This matters well beyond one retailer. Partnership ads are the format that turns creator posts into paid media, and Meta says they are on a $10 billion annual run rate. If fake creators can soak up that much budget, every brand buying creator content has a verification problem, and every real creator is competing against accounts that cost nothing to run.

The story moved from research to retreat in under a week. ORL could only see this because the EU's Digital Services Act forces large platforms to publish a public library of every ad they run. No equivalent database exists in the US, so nobody knows if the same pattern runs there.

Partnership ads in Ireland, Cyprus, Austria, Denmark, Latvia and Slovenia stopped almost entirely. Fortune noted that misleading-ad penalties there are strict, including possible criminal conviction in four of those countries.

Neither Temu nor Meta commented to Fortune. It is still unclear whether Temu ran the fake accounts on purpose or was paying scammers who gamed its program.

Partnership ads let a brand pay to boost a creator's post as if it were its own ad. The creator tags the brand and includes a shopping link. If the brand likes the post, it puts spend behind it. The creator is paid by contract or by a cut of sales.

The format works because a post from a person feels less like an ad. That same trust is what makes fake creators valuable. An AI-generated "person" posting product videos borrows the credibility of real creators without any of the cost.

Temu's use of the format was extreme. Partnership ads made up 65.8% of Temu's Meta ads, per ORL. Among typical advertisers the figure is about 2%. The spend was also concentrated: from January to April 2026, just 100 creators ran 74% of Temu's partnership ads in the region.

Meta disclosed in Q1 2026 that partnership ads were on a $10 billion annual run rate. ORL estimates Temu alone made up nearly 2% of Meta's European revenue in a typical quarter. Two outside ad experts Fortune consulted found ORL's estimates plausible.

The weak point is simple. The system checks whether a post performs, not whether the creator behind it is real.

ORL flagged accounts using signals any brand can check in minutes. None of them needs special tools.

After the story broke, ORL noticed another sign: most of these accounts stopped displaying the country they were based in.

One caveat. ORL's manager, Vendula Prokůpková, told Fortune some real people are among the top 100, though she estimated no more than 15 to 20%. Temu's full creator network is 12,000+ accounts, and many are legitimate. A single red flag is not proof. A cluster of them is.

Advertising through fake people is likely illegal in several jurisdictions. That is true even if a brand did not create the accounts itself. There is no evidence Temu's ads were fraudulent, and no regulator has ruled on the case yet.

UK and EU. Stuart Lester, who leads Mishcon de Reya's advertising group, told Fortune that presenting fake accounts as real people is misleading and likely breaches rules in the UK and the EU. The UK's Digital Markets, Competition and Consumers Act 2024 bans misleading advertising. The EU AI Act requires AI-generated content to be labeled. ORL has also asked the EU's Digital Services Act regulator to assess the risk of Temu's account network.

Pressure on Meta. Platforms are being pushed too. Poland's formal complaint seeks a €250 million fine against Meta, saying Meta removed only 10 of 122 fraudulent ads its cybersecurity team flagged (Net Influencer).

United States. The FTC's Consumer Reviews and Testimonials rule, effective October 21, 2024, is the closest US equivalent. It bans testimonials from people who do not exist, including AI-generated ones, when a business knew or should have known they were fake. The FTC's Q&A on the rule says a hired influencer's product post counts as a testimonial. The rule also bans buying fake indicators of influence, defined to include accounts not tied to a real person. Violations can bring civil penalties.

The practical takeaway: "we didn't know" is a weak defense when the red flags are public. A handle that changed 15 times is hard to miss.

For real creators, the lesson is that verifiable authenticity is becoming a selling point. Fake accounts cost almost nothing to run, post hundreds of times a day and never negotiate rates. On volume alone, a real creator cannot compete with that.

The market is starting to price authenticity in. At its LA Creators Summit on September 24, TikTok promoted TikTok One Plus, an invite-only tier with a "High-quality content creator" label for brands. Members earn 15% more on Custom Collab deals, per Net Influencer. Expect more platforms to add verification signals as brands demand proof.

AI is not the villain here. Luke Stillman of Madison & Wall told Fortune that AI-assisted production and performance-driven creative will only spread across the industry. The problem in Temu's case was not AI tools. It was accounts pretending to be people who do not exist.

What creators can do now:

Run these checks before putting spend behind any creator post, especially in partnership or whitelisting programs. Each maps to a red flag from the Temu case.

Did Temu create the fake accounts? It is not known. Fortune reported it is unclear whether Temu did this deliberately or was fooled by scammers exploiting its ad budget. Neither Temu nor Meta commented.

How much did Temu spend? Up to $962 million (about €830 million) on Meta ads in the UK and 27 EU countries over 16 months ending April 2026, per ORL's estimate based on impressions and average cost.

How many accounts were fake? ORL judged about 73 of the 100 most-used creator accounts likely fake. Temu's full creator network is 12,000+ accounts, many of them legitimate.

What are Meta partnership ads? A format that lets brands pay to boost a creator's post that tags them. Meta says it is on a $10 billion annual run rate.

Does this happen in the US? Nobody can tell yet. The research relied on the EU's public ad library, and the US has no equivalent.

Is it illegal to use AI influencers? Not in itself. The legal risk comes from presenting AI or fake accounts as real people without disclosure. This article is not legal advice, so check with counsel for your market.

How can brands spot a fake creator? Look for frequent handle changes, no identity verification, a location that doesn't match the audience, mismatched profiles and extreme posting volume.

Note on one figure: Fortune's two stories give different counts for Ya Lili's campaigns (109,541 and 278,000). Both cite about 225 a day, so this article uses the daily rate.
