Core Event: Platform Restrictions and Alleged Favoritism
Internal communications obtained by *Folha de S. Paulo* reveal that Meta’s Instagram algorithm limited the reach of President Luiz Inácio Lula da Silva’s posts during the election while recommending the profile of his opponent, Senator Flávio Bolsonaro, and the senator’s WhatsApp channel. The messages, reviewed on October 16, show engineers flagging the problem as urgent because it involved the sitting president’s account.
Background & Context
Brazil’s presidential election moved to a runoff on October 25 after the first round on October 4 left incumbent Lula with 45 % of the vote and Bolsonaro with 47 %. Lula’s campaign filed a complaint with the Superior Electoral Court (TSE), alleging that Meta’s algorithms suppressed his content and amplified Bolsonaro’s. The court, led by Justice Marco Aurélio Bellizze, ordered Meta to ensure identical treatment of both candidates and imposed a daily fine of 500,000 reais for non-compliance.
Data & Statistics
- Fine: 500,000 reais per day (Justice Bellizze).
- Legal challenges: 162 filings after the first round.
- Technical outage: On October 9, Meta engineers spent nearly 24 hours addressing a bug that prevented Lula’s Instagram posts from being boosted.
- Polls: Datafolha shows Bolsonaro at 51 % and Lula at 49 % of valid votes; a Quaest poll places them at 46 % versus 44 %.
Official Statements & Responses
- Justice Bellizze (TSE): Meta may not reduce the distribution of political content, restrict searches, or remove posts in a way that creates an imbalance; the AI tool must apply identical criteria.
- Lula’s campaign: Accuses Meta of removing share buttons, limiting reaction options, and suppressing view counts on the president’s posts. The campaign also noted that Meta’s AI on WhatsApp refused to generate campaign images for Lula while readily producing them for Bolsonaro.
Criticism & Opposition
Lula’s campaign, supported by digital watchdog groups such as Eko and CTRL + Z, argues that the platform’s selective restrictions constitute “algorithmic selectivity” that benefits Bolsonaro. Lawyers Gean Ferreira and Evelyn Santos described the impact as “unjustified reductions in reach” for Lula’s content, contrasted with “disproportionate and artificial reach” for Bolsonaro’s profiles. The internal messages reviewed by *Folha* corroborate staff awareness of the asymmetry, though they stopped short of admitting intentional bias.
Conflicting Reports & Gaps
Meta attributes the disruptions to worldwide technical glitches, anti-fraud filters, and a temporary bug affecting name-length processing. Lula’s team contends that the timing and pattern—simultaneous suppression of Lula’s posts and promotion of Bolsonaro’s profile—indicate selective impact rather than random failure. No public admission of deliberate interference has been made by Meta, and the court’s ruling focuses on outcomes rather than intent, leaving the precise cause unresolved.
Verbatim Quotes
- “Brazilian voters deserve facts, not a political narrative constructed by combining unrelated technical issues. Meta will continue to enforce its rules, comply with Brazilian electoral legislation, correct errors when they occur, and ensure a level playing field for everyone who uses our services,” — Flávio Bolsonaro, Senator.
- “I'm going to create Lula's Army, Navy and Air Force on WhatsApp; it's the cheapest way to campaign,” — Luiz Inácio Lula da Silva, President.
