Facebook Misses Election Misinfo in Brazil Ads

Facebook failed to detect blatant election-related misinformation in ads ahead of Brazil’s 2022 election, a new report from Global Witness has found, continuing a pattern of not catching material that violates its policies the group describes as “alarming.”

The advertisements contained false information about the country’s upcoming election, such as promoting the wrong election date, incorrect voting methods and questioning the integrity of the election — including Brazil's electronic voting system, The Associated Press said.

This is the fourth time that the London-based nonprofit has tested Meta's ability to catch blatant violations of the rules of its most popular social media platform— and the fourth such test Facebook has flubbed. In the three prior instances, Global Witness submitted advertisements containing violent hate speech to see if Facebook's controls — either human reviewers or artificial intelligence — would catch them. They did not.

“Facebook has identified Brazil as one of its priority countries where it’s investing special resources specifically to tackle election-related disinformation,” said Jon Lloyd, senior advisor at Global Witness. “So we wanted to really test out their systems with enough time for them to act. And with the US midterms around the corner, Meta simply has to get this right — and right now.”

Brazil's national elections will be held on Oct. 2 amid high tensions and disinformation threatening to discredit the electoral process. Facebook is the most popular social media platform in the country. In a statement, Meta said it has “ prepared extensively for the 2022 election in Brazil.”

“We’ve launched tools that promote reliable information and label election-related posts, established a direct channel for the Superior Electoral Court (Brazil's electoral authority) to send us potentially-harmful content for review, and continue closely collaborating with Brazilian authorities and researchers,” the company said.

In 2020 Facebook began requiring advertisers who wish to run ads about elections or politics to complete an authorization process and include “paid for by” disclaimers on them, similar to what it does in the US The increased safeguards follow the 2016 US presidential elections, when Russia used rubles to pay for political ads designed to stoke divisions and unrest among Americans.

Global Witness said it broke these rules when it submitted the test ads (which were approved for publication but were never actually published). The group placed the ads from outside Brazil, from Nairobi and London, which should have raised red flags.

It was also not required to put a “paid for by” disclaimer on the ads and did not use a Brazilian payment method — all safeguards Facebook says it had put in place to prevent misuse of its platform by malicious actors trying to intervene in elections around the world.

“What’s quite clear from the results of this investigation and others is that their content moderation capabilities and the integrity systems that they deploy in order to mitigate some of the risk during election periods, it’s just not working,” Lloyd said.

The group is using ads as a test and not regular posts because Meta claims to hold advertisements to an “even stricter” standard than regular, unpaid posts, according to its help center page for paid advertisements.

But judging from the four investigations, Lloyd said that's not actually clear.
“We we are constantly having to take Facebook at their word. And without a verified independent third party audit, we just can’t hold Meta or any other tech company accountable for what they say they’re doing,” he said.

Global Witness submitted ten ads to Meta that obviously violated its policies around election-related advertising. They included false information about when and where to vote, for instance and called into question the integrity of Brazil's voting machines — echoing disinformation used by malicious actors to destabilize democracies around the world.

In another study carried out by the Federal University of Rio de Janeiro, researchers identified more than two dozen ads on Facebook and Instagram, for the month of July, that promoted misleading information or attacked the country’s electronic voting machines.

The university’s internet and social media department, NetLab, which also participated in the Global Witness study, found that many of those had been financed by candidates running for a seat at a federal or state legislature.

This will be Brazil's first election since far-right President Jair Bolsonaro, who is seeking reelection, came to power. Bolsonaro has repeatedly attacked the integrity of the country's electronic voting system.

“Disinformation featured heavily in its 2018 election, and this year’s election is already marred by reports of widespread disinformation, spread from the very top: Bolsonaro is already seeding doubt about the legitimacy of the election result, leading to fears of a United States-inspired January 6 ‘stop the steal’ style coup attempt,” Global Witness said.

In its previous investigations, the group found that Facebook did not catch hate speech in Myanmar, where ads used a slur to refer to people of East Indian or Muslim origin and call for their deaths; in Ethiopia, where the ads used dehumanizing hate speech to call for the murder of people belonging to each of Ethiopia’s three main ethnic groups; and in Kenya, where the ads spoke of beheadings, rape and bloodshed.



China's Tencent Says AI Agents Showed Unintended Browsing Behavior

Tencent said on Friday that AI agents used to evaluate third-party models displayed web-browsing behavior not intended by the tech giant, in what appears to be the first known incident of rogue agent actions acknowledged by a major Chinese company.

The statement followed a report by AI-safety research group Swarmchasers on Wednesday, which said "rogue" agents running on infrastructure it linked to Tencent Cloud made repeated attempts between September 28 and October 8 to retrieve information from Alibaba's Amap, China's equivalent to Google Maps.

Tencent Hunyuan, the company's artificial ⁠intelligence unit, said in ⁠a post on X that the activity did not originate from its Hunyuan models. Its review found no evidence of deliberate targeting or coordination, Reuters quoted it as saying.

The Swarmchasers researchers said the agents sought information such as the commonly used entrances at Chinese parks, museums and zoos.

The actions are not as egregious as those disclosed by US AI companies which include the hack of ⁠open-source platform Hugging Face by an OpenAI agent and the lodging of a fake homicide tip by an Anthropic agent.

But the disclosure underscores research that shows Chinese AI agents can also misrepresent their identity, conceal failures and try to circumvent testing controls.

Tencent said it took the findings very seriously and was strengthening network access controls and agent monitoring.

Hunyuan is one of China's leading AI model developers, competing with in-house teams at rivals such as Alibaba and ByteDance. ByteDance this week announced the creation of a new unit focused on AI model and agent safety.

Swarmchasers said it used the ⁠word "rogue" to ⁠describe agents taking actions outside their intended scope or completing a task in unintended ways.

After routine automated requests were blocked, the agents tried other methods, including public web tools that could open pages and run code, routing requests through other websites and using Amap keys and security codes found in publicly available software code.

Swarmchasers said it found no evidence that the agents breached Amap's main anti-bot safeguards. Most of the 2,818 attempts it recorded either failed or returned anti-bot pages, login screens or blank results.

Some requests returned information through cached pages and intermediary services, including data on visitor arrivals at Chengdu Zoo, Swarmchasers said. The researchers said they could not determine whether an agent read the result or completed its task.

Anthropic co-founder Jack Clark renewed calls on Friday for regulating artificial intelligence, saying that allowing companies to continue to operate without robust legislation was like letting a race car loose on the streets at night without brakes.

"It's remarkable to me that the toys I buy for my children are regulated more than the literal super intelligence I work on at my day job," he told an event at the IMF-World Bank's Annual Meetings in Bangkok.

Clark said that US President Donald Trump, whose administration has called for the industry to police itself, was against the idea of regulation but that China was not, said AFP.

"I think it's Formula One at night without maybe brakes in the cars," he said.

He said the lack of clarity around the will for regulation meant "the Formula One car is roaring round and nobody seems to want to put up a guardrail?"

At an industry summit in Dublin on Wednesday, calls to prioritize safety in the development of powerful AI technology dominated the conversation.

Concerns about AI guardrails have soared after models developed by OpenAI and Anthropic were involved in security incidents during testing, piling on pressure to regulate the technology.

A recent Anthropic report suggested small AI models may be only months away from behaving like computer worms, copying themselves from one internet-connected device to the next.

Anthropic has been among those companies calling for governments to step in, even suggesting international coordination to slow down the whole industry -- including Chinese rivals.

That initiative has so far failed to materialize, with companies involved in a hyper-competitive race to attract as much investment as possible.

Meta ‌Platforms on Thursday released an open-weight version of its Muse Spark artificial intelligence model for coding and AI agents, expanding developers' ability to download and adapt the technology.

Open-weight models make trained parameters available for developers to modify, unlike proprietary models ‌that remain under ‌their creators' control. ‌They ⁠can offer businesses ⁠a lower-cost alternative to closed systems.

Meta said Muse Spark has 816 billion total parameters, with 42 billion active at a time, and ⁠can handle a context window ‌of up ‌to 1 million tokens.

The ‌model can run locally on ‌two Apple M5 Ultra Mac Studio computers and is also available through some API providers.

CEO ‌Mark Zuckerberg has argued that advanced AI should ⁠not be ⁠concentrated among a small number of companies.

While open-weight models can give companies greater control over their data, they can require significant computing resources and technical expertise to operate at scale.

In August, Meta released Muse Glimmer, a smaller open-weight model.
