Meta's independent Oversight Board says the company is once again falling short in protecting elections. The criticism comes days before the second round of Brazil's presidential election, in which Meta is also under the supervision of the electoral court.
The Oversight Board, the advisory body that rules on content moderation at Meta, published a statement on Tuesday about elections in Brazil and other forthcoming elections. According to the board, there are recurring problems: posts and accounts may be removed incorrectly, while other harmful content may remain online for too long.
The board referred in particular to an error in which advertising accounts for President Luiz Inácio Lula da Silva's campaign were restricted. Meta says an advert was incorrectly flagged as a possible attempt to impersonate a government programme. According to the company, the account was disabled for slightly more than an hour and then restored.
Meta denies having politically disadvantaged Lula or his opponent Flávio Bolsonaro. The company says various incidents had technical causes and that the same rules apply to all candidates. Meta also says a global problem with counting Instagram views did not limit the reach of political accounts.
According to Associated Press, Brazil's electoral court TSE had earlier ordered Meta to treat both campaigns equally. On Tuesday, the company told the court that measures had been introduced to comply with that decision. According to Associated Press, these include a system under which automatic blocks or restrictions on campaign accounts must be reviewed by people within two hours.
The discussion goes beyond a single error in an advertising account. The Oversight Board says Meta still has no public, verifiable metrics that would allow outsiders to assess how well moderation works during elections. According to the board, general figures, such as the numbers of accounts removed or adverts stored, do not sufficiently show where the system is failing.
At the same time, the TSE is supervising the use of artificial intelligence and WhatsApp channels in the campaign. The court wants voters to be able to assess both candidates under comparable conditions. Meta has pledged to retain data on certain campaign publications where a court order exists.
The Brazilian case is relevant to users in the Netherlands because the same tension is also present in Europe: platforms must counter political manipulation and disinformation, but automated systems can also affect legitimate political speech. The events in Brazil do not prove that Meta deliberately favoured one candidate. They do show how difficult it is to identify, explain and correct errors quickly during an election period.

One story, several perspectives
What is established
- Brazil's electoral court ordered Meta to treat the campaigns of Lula and Flávio Bolsonaro equally.
- Meta says technical errors and moderation interventions affected both campaigns and denies political bias.
- The Oversight Board says that errors in election moderation can both suppress legitimate political speech and allow harmful content to remain online.
Left
Arguments Large platforms have so much influence over elections that they must be actively held to account. If algorithms or fraud filters affect a campaign, rapid human review and full transparency should be mandatory.
Values Equal political participation, protection against the concentration of power among technology companies, and accessibility of public debate.
Consequences Without strict oversight, errors could disproportionately affect smaller or progressive campaigns; insufficient enforcement could reinforce disinformation and abuse of power.
Centre
Arguments The electoral court must safeguard a level playing field, but governments should be cautious about directly intervening in moderation. Independent audits, clear procedures and rapid avenues of appeal offer a workable compromise.
Values Institutional reliability, legal certainty, enforceability, and protection of both electoral integrity and freedom of expression.
Consequences A transparent oversight system can limit errors without placing platforms entirely under political control; it does, however, require measurable standards and supervision.
Right
Arguments Platforms and courts must take care that combating disinformation does not turn into political censorship. The government should not determine which legitimate campaign messages voters may see.
Values Freedom of expression, political competition, limited government power, and voters' individual responsibility.
Consequences Heavy obligations could lead platforms to remove too much or block political content as a precaution; at the same time, action against proven fraud remains necessary.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

Editor's note
It is certain that the Oversight Board identified recurring moderation errors on 20 October and that Meta says it is complying with an order from Brazil's electoral court. It remains uncertain whether the errors were politically biased; no independent evidence has been found for this.Sources
