X Pledges Faster Removal of Hate Speech and Terror Content for UK Regulators

On 15 May 2026, the UK communications regulator Ofcom announced that X had committed to a package of measures targeting illegal hate speech and terrorist content on the platform [1][2]. The agreement represents the most concrete set of content moderation benchmarks X has accepted from any regulator since Elon Musk's acquisition in October 2022.

The central question is straightforward: can a platform that shed 30% of its trust and safety workforce actually meet those benchmarks — and what happens if it cannot?

What X Has Pledged

X's commitments, negotiated with Ofcom under the framework of the Online Safety Act 2023, include five measurable elements [2][7]:

• 24-hour average review time for suspected illegal hate speech and terrorist content flagged by users or partner organisations
• 85% of flagged content assessed within 48 hours
• Quarterly performance reports submitted to Ofcom over the following 12 months
• Restricting UK access to accounts operated by or on behalf of organisations proscribed under British terrorism law
• Engaging external experts to redesign X's content reporting flow, which civil society groups have called opaque

Suzanne Cater, Ofcom's director of online safety, stated that "terrorist content and illegal hate speech is persisting on some of the largest social media sites" [7].

How X Compares to Other Platforms

X's pledged benchmarks are notably less aggressive than what competitors have already demonstrated.

TikTok's most recent EU transparency report showed a median response time of 3.05 hours for hate speech reports, with 88.7% of user-flagged content reviewed within 24 hours [8]. Under the EU Code of Conduct on Countering Illegal Hate Speech Online, major platforms including Meta and YouTube have committed to reviewing the "majority" of flagged content within 24 hours [9]. X's 48-hour window for 85% of content is, by these standards, the least demanding benchmark among major platforms.

Ofcom has not published a single uniform response-time benchmark under the Online Safety Act. Instead, it has adopted a service-specific approach, requiring each platform to demonstrate "systems and processes" proportionate to its risk profile [5][10]. X's 24-hour average and 48-hour threshold were negotiated rather than imposed by statute.

The Workforce Behind the Promise

The credibility of X's pledge rests on its operational capacity — and the numbers raise questions.

Data as of Sep 4, 2024CSV

Between October 2022 and May 2023, X's total trust and safety workforce dropped from 4,062 to 2,849 workers and contractors globally — a 30% reduction [3][4]. The cuts fell disproportionately on specialists:

• Safety engineers: reduced from 279 to 55 (an 80% cut) [3]
• Full-time content moderators: reduced from 107 to 51 (a 52% cut) [3]
• Contract moderators: reduced from 2,613 to 2,305 (a 12% cut) [3]

By September 2024, X had begun posting new positions across safety and cybersecurity teams [6], but neither the scale of rehiring nor the current headcount has been publicly disclosed.

X has said it relies increasingly on automated systems — machine learning classifiers that either action content directly or surface it for human review [11]. The platform's most recent transparency report, covering H1 2024, stated that 0.0123% of posts violated its rules, with hateful conduct accounting for nearly half of all violations (0.0057% violation rate) [11].

Critics note that X suspended only 0.004% of users reported for hate speech in H1 2024, compared to the 111,000 users Twitter suspended for hateful conduct in H1 2022 before the acquisition [11][12].

Content Volumes and Proactive Detection

X's transparency data does not break out UK-specific removal figures in a way that allows direct comparison with Ofcom's forthcoming requirements. Globally, X reported 81 million user-generated reports in H1 2024 [11]. Of the content ultimately actioned, X states that its systems use a combination of machine-learning detection and human review, with proactive detection surfacing some content before user reports [11].

By contrast, TikTok has reported that 96.3% of content it removed for hate speech violations was detected proactively — before any user flagged it [8]. X has not published a comparable proactive-detection ratio.

An independent study published in February 2025 by Euronews, drawing on academic research, found that hate speech on X was 50% higher than pre-acquisition levels [12]. The study measured prevalence rather than response times, but it establishes the context within which X's UK pledge operates.

Penalties: What Ofcom Can Actually Do

Under the Online Safety Act, Ofcom can impose financial penalties of up to £18 million or 10% of qualifying worldwide revenue, whichever is greater [5][13]. Fines can compound daily for ongoing non-compliance [5]. In the most serious cases, Ofcom can apply to the courts to block a service from operating in the UK [13].

As of early 2026, Ofcom had launched five enforcement programmes and opened 21 investigations [5]. Its largest fines to date have been relatively modest: £1 million against AVS Group for inadequate age checks, and £20,000 against 4chan for failing to comply with information requests [5][14]. No fine has yet been imposed on a platform of X's scale under the Online Safety Act.

The gap between statutory maximum and actual enforcement practice is significant. Ofcom has acknowledged it is in an early phase of building enforcement precedent, with penalties expected to escalate throughout 2026 [5][10].

Is the Pledge Legally Binding?

This is a critical distinction. X's commitment is a negotiated assurance accepted by Ofcom — not a formal statutory undertaking or consent order [7][14]. Ofcom's enforcement guidance describes a spectrum of tools: it can accept "commitments or assurances to remedy compliance concerns" in lieu of opening formal investigations [14].

Ofcom's formal investigation into X remains open [7]. The pledge functions as a parallel compliance remediation process — similar to the approach Ofcom took with Snap over illegal harms risk assessments [14]. If X fails to meet the benchmarks in its quarterly reports, Ofcom retains the authority to escalate to formal investigation, enforcement notices, and ultimately fines.

However, the pledge itself does not create an independent cause of action. There is no defined third-party audit mechanism written into the agreement. Ofcom receives X's self-reported quarterly data, but the question of whether an independent auditor will verify that data remains unresolved [7][10].

Who Decides What Qualifies as Illegal?

X's pledge covers two specific categories defined under UK law [2][7]:

1. Illegal hate speech — as defined under the Public Order Act 1986 (incitement to racial and religious hatred) and the Communications Act 2003
2. Terrorist content — material posted by or on behalf of organisations proscribed under the Terrorism Act 2000

The determination process works in layers. X's automated classifiers make initial triage decisions. Flagged content is then reviewed by human moderators against UK legal definitions. Ofcom does not itself make content removal decisions — it oversees whether the platform's systems are adequate to meet its legal obligations [7][10].

To inform its enforcement, Ofcom has worked with expert organisations including the Antisemitism Policy Trust, Community Security Trust, Center for Countering Digital Hate, HOPE not hate, Tech Against Terrorism, and Tell MAMA [2]. These groups provide evidence about the prevalence of illegal content but do not have removal authority.

The Free Speech Tension

Civil liberties organisations have raised substantial objections to the broader Online Safety Act framework within which X's pledge sits.

In December 2025, the Electronic Frontier Foundation, Open Rights Group, Big Brother Watch, and Index on Censorship jointly called on the UK government to reform or repeal the Act [15]. Their concerns centre on provisions requiring platforms to proactively censor content posing a "material risk of significant harm to an appreciable number of adults" — language they argue will "disproportionately impact the voices of marginalised people" [15][16].

Article 19, an international freedom of expression organisation, downgraded the UK below its threshold for "Open" status in its Global Expression Report — the first such downgrade since the index began [15]. The US State Department's 2024 human rights report noted that "numerous individuals were arrested for online speech" in the UK [15].

Danny Stone of the Antisemitism Policy Trust described X's package as "a positive step" but noted X continues "failing in so many regards" to address racism on the platform [7]. This captures the dual criticism X faces: too much moderation from one direction, too little from another.

Breitbart characterised the agreement as X "committing to crackdown on 'hate speech'" with scare quotes indicating scepticism about the category's coherence [17]. The underlying concern — that vague definitions create space for political speech suppression — has support from academic research. A CEPR study found that removing toxic content from a representative sample of 5 million US political tweets was equivalent to "eliminating 4 out of 67 topics from the debate" [18].

The False Positive Problem

Faster automated removal increases the rate at which legitimate content is incorrectly suppressed. Research published in the Harvard Kennedy School Misinformation Review found that algorithmic moderation systems "are unable to reliably determine a person's state of mind" — meaning that swear words, personal accounts of experiencing racism, or satirical uses of harmful language routinely trigger false positives [19].

A 2025 ACM study on identity-related speech suppression in AI moderation systems documented that over-cautious filtering "doesn't merely muffle hate; it can also erase legitimate dissent," with the impact distributed unevenly across identity groups [20]. Cultural context failures — where a system trained on one linguistic environment misreads another — compound the problem in a multilingual platform like X.

X has not published false-positive rates for its UK content moderation. Neither has Ofcom established a benchmark for acceptable false-positive thresholds.

Timeline and Accountability

X's quarterly reporting obligation runs for 12 months from May 2026, meaning the first dataset will cover roughly June–August 2026 [7]. Ofcom's broader categorisation register — which will formally classify platforms by risk tier — is expected in July 2026 [10][21].

The convergence of these timelines means X's first quarterly report will arrive just as Ofcom finalises which platforms face the most stringent requirements. If X's self-reported data shows non-compliance, Ofcom can escalate to formal investigation.

Concurrent regulatory actions against X are active in the European Commission, Australia, and Singapore [7]. Whether Ofcom's approach produces faster results than these parallel proceedings will test the effectiveness of the Online Safety Act's enforcement model.

What Remains Unresolved

Several questions remain open:

• Independent verification: No third-party auditor has been named to validate X's quarterly data submissions
• The Grok investigation: A separate Ofcom probe into AI-generated sexualised imagery created with X's Grok chatbot remains unresolved [7]
• Staff capacity: X has not disclosed its current trust and safety headcount or the ratio of automated-to-human review for UK-specific content
• Proactive detection rates: Unlike TikTok's 96.3% proactive detection figure, X has published no equivalent metric for hate speech
• Appeal mechanisms: The pledge does not address how users whose content is incorrectly removed can appeal, or what recourse exists for false positives

The gap between pledge and performance will become measurable within months. Whether Ofcom treats a voluntary assurance with the same weight as a formal undertaking — and whether quarterly self-reporting constitutes genuine accountability — will determine whether this agreement represents a regulatory advance or a delay tactic by a platform under pressure from multiple jurisdictions simultaneously.
