The watchdog said its analysis of nearly eight million Facebook comments directed at 100 members of Congress found a significant rise in threatening and abusive content during the six months following Meta’s policy changes compared with the previous six-month period.

According to the report, violent threats against lawmakers from both major political parties, including explicit calls for murder, increased fourfold after the moderation rollback. Harassment more than doubled, while racist and gender-based abuse also rose substantially.

The CCDH said the increase extended beyond lawmakers, with comments advocating violence against President Donald Trump also rising after the changes. The organization argued that reduced enforcement of platform rules against threats, hate speech and harassment contributed to a more hostile online environment.

“When platforms stop enforcing their own rules against threats, hate, and harassment, they become complicit in normalizing intimidation and harassment of elected officials,” CCDH Chief Executive Imran Ahmed said in a statement accompanying the report.

Meta disputed suggestions that harmful content had increased on its platforms. A company spokesperson said Meta regularly publishes transparency reports tracking policy violations and maintained that the prevalence of hateful conduct did not rise during 2025.

The company said it had not received the CCDH report before publication and therefore could not specifically address its findings.

The debate comes amid broader concerns about the safety of public officials in the United States. Lawmakers, election officials and other public figures have reported increasing levels of threats and intimidation in recent years, prompting renewed scrutiny of online platforms and their role in moderating harmful content.

Republican Senator John Curtis of Utah described the findings as troubling, particularly against a backdrop of recent politically motivated violence. He said reductions in oversight of violent, hateful and harassing content could contribute to an increase in such behavior online.

Meta’s moderation changes followed a broader shift in policy that included ending partnerships with independent fact-checkers in the United States in January 2025 and adopting a Community Notes system that relies on users to add context to disputed claims. The approach mirrors a model popularized by Elon Musk’s social media platform X.

The policy adjustments were viewed by critics as part of a wider effort to address longstanding complaints from conservative groups that fact-checking systems restricted free expression and disproportionately affected right-leaning viewpoints.

Meta also eased some restrictions governing discussions related to gender and sexual identity, drawing criticism from advocacy organizations that warned the changes could increase exposure to harmful and discriminatory content.

The CCDH report is likely to intensify debate over the balance between free expression and platform safety as policymakers, technology companies and civil society groups continue to grapple with the impact of online speech on democratic institutions and public officials.

Curtis, speaking alongside fellow lawmakers including Jeanne Shaheen, said Taiwan should draw lessons from Hong Kong, where Beijing imposed a sweeping national security law in 2020 following unrest, a move critics say curtailed freedoms.

The visit comes as President Lai Ching-te seeks approval for an additional $40 billion in defence spending, a proposal backed by Washington but currently stalled in the opposition-controlled parliament.

Taiwan’s government says the funding is necessary to strengthen deterrence against China, which claims the island as its territory. Opposition parties have expressed support in principle for defence measures but have resisted approving what they describe as open-ended commitments.

Curtis said Taiwan risked misjudging Beijing’s intentions if it ignored the trajectory of Hong Kong since its return to Chinese rule in 1997 under a framework guaranteeing autonomy.“My biggest worry for Taiwan is that they underestimate the intentions of China,” Curtis said, urging vigilance despite aspirations for peace.

China has simultaneously stepped up engagement with Taiwan’s opposition. Beijing has invited Cheng Li-wun, leader of the Kuomintang, to visit, a trip she has described as a “peace mission.”

Taiwan’s Mainland Affairs Council said China’s objective of annexation had not changed and cautioned against what it called “illusions” about peace, reflecting ongoing tensions across the Taiwan Strait.
