Facebook approved a series of online ads promoting violence in Brazil, days after protesters ransacked government buildings, according to a new report.

Earlier this month, thousands of supporters of Brazil’s far-right former President Jair Bolsonaro stormed the nation’s congress, supreme court, and presidential palace in an attack lasting more than three hours, Reuters said.

In an attempt to stem the flow of posts inciting violence online, Facebook’s parent company Meta said it had designated Brazil as a “temporary high-risk location” and removed content calling for people to take up arms or forcibly invade government buildings.

However, four days after the uprising, human rights organization Global Witness found Facebook was still allowing ads containing death threats and other calls to violence on its platform.

Using fake accounts, the group submitted 16 bogus ads to run on the platform, 14 of which were approved for publication.

Among the approved ads were messages which read, in Portuguese: “We need to unearth all the rats that have seized power and shoot them”, “We need a military revolution to restore the rule of law”, and “Death to the children of Lula voters”.

Leftist President Luiz Inacio Lula da Silva took office on Jan. 1 after defeating Bolsonaro in a runoff election in October. Bolsonaro refused to concede defeat, however, and some supporters claimed the election was stolen.

Global Witness also submitted the ads for approval on YouTube, but the video-sharing platform immediately suspended the group's accounts.

Global Witness said it withdrew the ads from Facebook before any other users could see them.

“In the aftermath of the violence in Brasilia, Facebook said they were ‘actively monitoring’ the situation and removing content in violation of their policies. This test shows how poorly they’re able to enforce what they say,” said Rosie Sharpe, digital threats campaigner at Global Witness.

“YouTube’s much stronger response demonstrates that the test we have set is possible to pass.”

Meta spokesperson Mitch Henderson said Global Witness’ small sample of ads was not representative of how the company enforced its policies at scale.

“Like we’ve said in the past, ahead of last year’s election in Brazil, we removed hundreds of thousands of pieces of content that violated our policies on violence and incitement and rejected tens of thousands of ad submissions before they ran.

“We use technology and teams to help keep our platforms safe from abuse and we’re constantly refining our processes to enforce our policies at scale.”



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.
