The Workers' Party (PT), led by Brazilian President Luiz Inácio Lula da Silva, has formally accused Meta—the parent company of Facebook, Instagram, and WhatsApp—of interfering in the country's democratic process. The campaign claims that Meta has restricted the reach and visibility of Lula’s official content as the October 25 presidential runoff against Senator Flávio Bolsonaro approaches.

In response to these allegations, the PT stated it intends to bring the matter before the Organization of American States (OAS) to seek international scrutiny of the platform's content moderation practices. The party argues that these algorithmic restrictions constitute an attempt to influence the election outcome by limiting the candidate's ability to communicate directly with voters.

Meta has categorically denied these accusations. The company maintains that its content moderation policies are applied neutrally and are designed to combat misinformation and platform abuse rather than target specific political campaigns. As of now, no specific evidence of a coordinated effort to suppress the campaign has been verified by independent third parties, and the company has not provided further details on the specific moderation actions the PT is contesting.
