TikTok's algorithms are very good at finding videos to keep people glued to their phone screens for hours on end. What they are not so good at, a new report has found, is detecting ads that contain blatant misinformation about U.S. elections.
That's despite TikTok having banned all political advertisements from its platform in 2019.
The report raises fresh concerns about the wildly popular video-sharing app's ability to catch election falsehoods at a time when a growing number of young people use it not just for entertainment, but also for . The nonprofit Global Witness and the Cybersecurity for Democracy team at New York University published the report Friday.
Global Witness and NYU tested whether some of the most popular social platforms 鈥 Facebook, YouTube and TikTok 鈥 can detect and take down false political ads targeted at U.S. voters ahead of next month's midterm elections. The watchdog group has done similar tests in , , and with ads containing hate speech and disinformation, but this is the first time it has done so in the United States.
The U.S. ads included misinformation about the voting process, such as when or how people can vote, as well as about how election results are counted. They were also designed to sow distrust about the democratic process by spreading baseless claims about the vote being 鈥渞igged鈥 or decided before Election Day. All were submitted for approval to the social media platforms, but none were actually published.
TikTok, which is owned by Chinese company ByteDance, performed the worst, letting through 90% of the ads the group submitted. Facebook fared better, catching seven out of 20 false ads 鈥 in both English and Spanish.
Jon Lloyd, senior advisor at Global Witness, said TikTok's results, in particular were 鈥渁 huge surprise to us" given that the platform has an outright ban political advertising.
In a statement, TikTok said it bans and prohibits election misinformation and paid political ads from its platform.
鈥淲e value feedback from NGOs, academics, and other experts which helps us continually strengthen our processes and policies," the company said.
Facebook's systems detected and took down the majority of the ads Global Witness submitted for approval.
鈥淭hese reports were based on a very small sample of ads, and are not representative given the number of political ads we review daily across the world," Facebook said. 鈥淥ur ads review process has several layers of analysis and detection, both before and after an ad goes live.鈥 It added that it invests 鈥渟ignificant resources" to protect elections.
YouTube, meanwhile, detected and took down all of the problematic ads, and even suspended the test account Global Witness set up to post the fake ads in question. At the same time, however, the Alphabet-owned video platform did not detect any of the false or misleading election ads the group submitted for approval in Brazil.
鈥淪o that goes to show that there鈥檚 a real global discrepancy in their ability to enforce their own policies," Lloyd said.
Google said it has 鈥渄eveloped extensive measures to tackle misinformation鈥 on its platforms, including false claims about elections and voting.
鈥淚n 2021, we blocked or removed more than 3.4 billion ads for violating our policies, including 38 million for violating our misrepresentation policy," the company said in a prepared statement. 鈥淲e know how important it is to protect our users from this type of abuse 鈥 particularly ahead of major elections like those in the United States and Brazil 鈥 and we continue to invest in and improve our enforcement systems to better detect and remove this content.鈥
Lloyd said that ramifications of a failure to control misinformation would be widespread.
鈥淭he consequences of inaction could be disastrous for our democracies and our planet and our society in general," Lloyd said. 鈥淚ncreasing polarization and all of that. I don鈥檛 know what it鈥檚 going to take for them to take it seriously."
