Two weeks before the US presidential election, the Oversight Board says it has “serious concerns” about Meta’s content moderation systems in “electoral contexts,” and that the company risks the “excessive removal of political speech” when it over-enforces its rules. The admonishment came as the board weighed in on a case involving a satirical image of Vice President Kamala Harris and her running mate, Minnesota Governor Tim Walz.

Meta originally removed the post, shared on Facebook in August, that showed an edited version of a movie poster from Dumb and Dumber. The original 1994 movie poster shows the two main characters grabbing each other’s nipples through their shirts. In the altered version, the actors’ faces were replaced by Harris and Walz.

According to the Oversight Board, Meta cited its bullying and harassment rules, which includes a provision barring “derogatory sexualized photoshop or drawings.” The social network later restored the post after it drew attention from the Oversight Board, and the company acknowledged the satirical image didn’t break its rules because it didn’t depict sexual activity.

Despite Meta’s reversal, the board says the case suggests larger issues in how Meta handles posts dealing with election-related content. “This post is nothing more than a commonplace satirical image of prominent politicians and is instantly recognizable as such,” the board wrote. “Nonetheless, the company’s failure to recognize the nature of this post and treat it accordingly raises serious concerns about the systems and resources Meta has in place to effectively make content determinations in such electoral contexts.”

It’s unusually direct criticism from the Oversight Board, which released its analysis of the case in a summary decision, which comes without the group’s typical laundry list of recommendations for the social media company. The board has previously pushed Meta its rules around satirical content.The latest case highlights another issue that many of the company’s users have also complained about: over-enforcing its rules.

“In this case, however, the Board highlights the overenforcement of Meta’s Bullying and Harassment policy with respect to satire and political speech in the form of a non-sexualized derogatory depiction of political figures,” the board wrote. “It also points to the dangers that overenforcing the Bullying and Harassment policy can have, especially in the context of an election, as it may lead to the excessive removal of political speech and undermine the ability to criticize government officials and political candidates, including in a sarcastic manner.”
