Temu appears to have largely stopped funding a network of fake accounts on Meta’s platforms in the days after it was first exposed by Fortune.

Temu had spent nearly $1 billion funding partnership ads with various influencers and creators on Instagram and Facebook, targeting users in the U.K. and all 27 EU countries, according to Online Risk Labs, a Czech-based social media research group. ORL examined a sample period of Temu’s advertising activity over 16 months ending in April 2026.

Around 73 of the 100 influencers whose pages featured the most Temu ads were probably fake, according to ORL. The accounts often had nonsensical names, were based in China, Russia, Bangladesh, or Iran, and some of them frequently changed names—all symptoms of inauthentic activity, according to ORL.

These 100 accounts participated in more than 1.4 million partnership ads, achieving a cumulative reach of almost 17 billion pairs of eyeballs, ORL told Fortune. (Meta’s partnership ad program allows influencers to create content that promotes a brand, tagging the company in each post. If the company likes the content, it can pay to boost it just like a paid ad. Creators get a cut of the budget. Meta disclosed earlier this year that partnership ads were on course for a $10 billion annual run rate across Facebook and Instagram.)

Fortune’s story on the fake account network ran on Aug. 31. At that time, Temu was running 4,900 separate partnership campaigns a day on the network.

By Sept. 4, 90 accounts suddenly featured zero advertising from Temu. Of the top 100 accounts, 54 stopped using partnership ads almost immediately after Aug. 31. (Temu’s entire network of creators involves 12,000 or more accounts, many of which are legit.) Overall, the number of partnership ads run by Temu almost halved after Fortune’s story.

The biggest account, “Ya Lili,” had 183,000 followers on her @findgadgetswithme Instagram account and a further 129,000 followers on Facebook, where she went by the name “Must good.” Ya Lili’s content ran in 278,000 Temu ad campaigns in ORL’s study period—about 225 campaigns per day.

Her account is almost certainly a fake. By Sept. 4, only five ads from Ya Lili appeared on Meta’s platforms, probably as remnants from previously scheduled ad buys. Ya Lili previously posted multiple times per day, but she stopped posting entirely on Sept. 7.

Neither Temu nor Meta responded to messages requesting comment.

“When you look at their Instagram accounts, you can see that they have not published any new posts/reels since two weeks or so. These are predominantly the accounts based in Russia, with some also based in the United States or China,” ORL manager Vendula Prokůpková told Fortune. “We also noticed that most of the Instagram accounts of these ‘creators’ no longer display information about the country the account is based in.”

Temu’s ad budget appears to have been maintained for legitimate creators. “Across all of its pages, weekly ads went from 166,523 in the week of 17 August to 147,013 in the week of 7 September,” ORL said in a follow-up to its original study. “Partnership ads over the same weeks went from 115,114 to 64,008.”

Partnership ads in Ireland, Cyprus, Austria, Denmark, Latvia, and Slovenia ceased almost entirely, ORL said. It is not clear why. The laws against misleading advertising in those jurisdictions are very strict, however. In Ireland, Denmark, Cyprus, and Austria, penalties can include criminal conviction and imprisonment. In the others, consumers have the right to sue companies that publish misleading ads, and cases can result in companies being forced to pay a percentage of their revenues.
