A presidential campaign is accusing one of the world’s most powerful tech platforms of tilting the electoral playing field. Brazil’s top electoral court is demanding answers within 48 hours.
Lula’s Workers’ Party filed complaints with the Superior Electoral Court (TSE) and the National Data Protection Authority (ANPD), alleging that Meta restricted its campaign activity on Instagram and Facebook in ways that could have benefited rival Flávio Bolsonaro. Meta called those allegations false.
What the Campaign Claims
Lula’s team reports a pattern of disruptions that, the campaign argues, no other major Brazilian candidate appears to have faced.
The campaign reported three specific disruptions: paid promotion of Instagram feed posts was blocked, the campaign’s advertising account was disabled, and video view counts failed to register on at least one post. Meta attributed each episode to “technical problems,” according to the campaign.
An internal Workers’ Party analysis found that Flávio Bolsonaro’s page averaged 2.96 times more engagement than Lula’s, despite having 17.2% fewer followers. That same internal report put Bolsonaro’s normalized engagement rate at approximately 10.23% against Lula’s 2.86%.
This is a PT survey, not an independent audit. The disparity does not by itself establish that Meta altered distribution to favor Bolsonaro. Content strategy, posting frequency, audience composition, and timing all affect engagement figures.
The campaign’s core argument is simpler: Meta has not demonstrated that comparable problems struck other Brazilian candidates.
Meta’s Response
The company says the reported failures were not limited to Brazil or to any specific account.
According to AFP, Meta stated that “many of the technical issues mentioned did not affect only Brazil or specific accounts.” The company also said it complies with electoral regulations and is committed to equal platform access for all candidates.
What Regulators Are Doing
Brazil’s electoral court is treating the complaints as serious enough to warrant formal clarification, though a request for information is not a finding of wrongdoing.
According to O Globo and CNN Brasil, the TSE asked Meta to address four specific questions:
- Whether Lula’s posts experienced reduced distribution
- Why video metrics showed anomalies
- Why the campaign’s advertising account was disabled
- Whether automated accounts promoted Flávio Bolsonaro while simultaneously targeting Lula
The ANPD was contacted separately on data governance grounds. Neither body has issued findings, and the inquiry is not a ruling.
Why Meta’s Explanation Faces Scrutiny
Meta’s record gives regulators and campaigns reason to verify explanations rather than accept them.
Cambridge Analytica harvested data from tens of millions of Facebook users for political targeting, an episode documented in a 2019 FTC enforcement action against the firm. That same year, Facebook, Inc., now operating as Meta, paid a $5 billion penalty to the U.S. Federal Trade Commission over allegations that it misled users about privacy controls.
Those earlier events do not connect to or explain the current Brazilian situation. They do help explain why a company response of “technical problem” requires documentation rather than assumption.
What Comes Next
The TSE’s conclusions could shape how much operational transparency Meta must provide during future Brazilian elections.
Until those findings arrive, one fact is confirmed: a presidential campaign and a tech platform are telling two very different stories about what happened to Lula’s reach. Brazil’s electoral court has decided that difference is worth investigating.
