Content Moderation by Registries Where Lines Are Drawn and Moved

The question of how and whether registries should engage in content moderation has become one of the most contentious issues in the governance of the domain name system. At its core, the DNS was designed to be neutral infrastructure, a technical addressing layer that translated human-readable names into numerical IP addresses. Registries were intended to manage this layer in a predictable and impartial way, maintaining stability and security without becoming arbiters of what content could or could not exist on the internet. Yet over the past decade, registries have been pushed into the center of content debates, with governments, advocacy groups, and even their own contractual partners demanding that they take action against domains associated with illegal, harmful, or controversial material. The result has been a gradual and uneven shift from neutrality toward selective enforcement, with the lines of responsibility constantly contested, redrawn, and shifted according to political, social, and economic pressures.

One of the first major turning points came with high-profile cases involving extremist content and child exploitation. While hosting providers and platforms were the more obvious points of intervention, law enforcement and advocacy groups realized that removing content at the hosting level often led to whack-a-mole scenarios, with sites reappearing under new hosts. Targeting domains themselves appeared more definitive: without a resolvable domain, websites became significantly less accessible to ordinary users. Registries and registrars thus became points of pressure, asked to suspend domains or refuse registrations linked to illegal activities. Initially, such interventions were narrowly framed around universally condemned content, such as domains distributing child sexual abuse material or sites clearly engaged in fraud. Few objected to these uses of DNS leverage, and registries could justify them as exceptional measures consistent with public safety and legal compliance.

But as the practice gained visibility, the range of demands widened. Advocacy organizations began calling for domain suspensions against sites accused of hate speech, harassment, or disinformation. Governments requested takedowns of domains linked to terrorism or political extremism, often based on legal definitions that varied widely across jurisdictions. Intellectual property groups pressured registries to take down domains associated with counterfeit goods or piracy. Even private actors, such as payment processors and advertisers, began to influence domain enforcement indirectly, refusing to work with registries perceived as tolerating controversial content. Each new category of enforcement moved the line further from the original conception of neutral infrastructure, embedding registries in debates over freedom of expression, legality, and morality.

The 2017 case of The Daily Stormer, a neo-Nazi website, crystallized the issue. After hosting providers cut ties with the site, attention turned to its domain registrations. Multiple registrars refused to continue serving the domain, leading to the site’s eventual difficulty in maintaining visibility on the open web. This episode demonstrated that domain intermediaries could effectively de-platform even the most resilient websites. It also highlighted the discretion registries and registrars wielded, since no legal mandate required them to suspend the domain. The action was voluntary, driven by reputational concerns and public pressure. This marked a shift: the DNS was no longer seen merely as a neutral technical layer but as a governance layer, one that could be mobilized against content deemed unacceptable by segments of society.

Such discretion has proven double-edged. On one hand, registries have used it to align with broadly shared norms, taking action against sites that few defend. On the other, it has raised concerns about the concentration of power in a small number of private companies. Many registries are monopolistic within their namespaces—there is only one operator for .com, .org, or .xyz—giving them immense leverage over the accessibility of domains. Unlike platforms such as social media companies, which operate in a competitive environment, registries have exclusive control over their TLDs. If they decide to deny or suspend a domain, registrants have no alternative provider within that namespace. Critics argue that this makes registry-level moderation particularly fraught, as it bypasses competition and choice, effectively erasing digital presence within a coveted extension.

The role of ICANN has further complicated matters. While ICANN insists that it does not act as a regulator of content, its contracts with registries and registrars include provisions requiring them to investigate and respond to abuse. The definition of abuse, however, has expanded over time, encompassing not only technical threats like spam and malware but also broader categories such as phishing, fraud, and sometimes even content-related harms. The ambiguity of these contractual obligations gives registries wide latitude to determine their policies. Some adopt minimalist stances, intervening only when compelled by clear legal orders. Others adopt expansive policies, proactively suspending domains tied to activities they deem harmful. This variation creates a fragmented landscape, where registrants may face very different risks depending on the policies of the registry governing their chosen TLD.

Geopolitics has added another layer of complexity. Governments increasingly see registries as levers of enforcement, demanding compliance with domestic laws that may conflict with international norms. A registry based in the United States may receive takedown requests from European authorities citing hate speech laws, while one based in Europe may face demands from U.S. agencies targeting piracy or sanctions violations. The location of a registry’s jurisdiction thus determines which pressures it faces most acutely. Some registries have resisted extraterritorial demands, insisting on adherence to domestic law only, while others have yielded to global pressure campaigns. This patchwork of practices underscores how content moderation at the registry level has become a site of international contestation, with no consistent framework governing the balance between sovereignty, freedom of expression, and security.

The economic dimension cannot be ignored. Registries are commercial entities, often motivated by revenue maximization and reputation management. Being seen as a haven for harmful content can alienate corporate partners, advertisers, and governments, threatening business sustainability. Conversely, being too aggressive in content moderation can alienate registrants, who may view the registry as unreliable or politically biased. Striking the balance is difficult, and the line between principled policy and opportunistic risk management is often blurred. In practice, many registries act reactively, suspending domains only when controversies become highly visible, rather than adopting consistent proactive policies. This reactive mode ensures survival but exacerbates unpredictability for registrants, who cannot be certain when or why their domains might be at risk.

The lines of moderation are further moved by crises. Events such as terrorist attacks, pandemics, or election cycles create surges of pressure on registries to act. Domains accused of spreading disinformation about vaccines, for example, have been flagged by health authorities and advocacy groups, with some registries taking them down. During conflicts, domains linked to sanctioned states or propaganda outlets have faced suspension under government directives. These episodic expansions of registry intervention raise the question of whether crisis-driven exceptions gradually normalize into routine practice. What begins as an extraordinary response to a global emergency can set precedents for future interventions, subtly shifting the baseline of what is considered legitimate use of registry power.

For registrants, the uncertainty surrounding registry moderation is a form of risk. Owning a domain is not merely a technical allocation but an investment of identity, branding, and communication. If that asset can be suspended at the discretion of a registry, subject to shifting social and political pressures, the stability of the DNS as a platform for expression and commerce is undermined. Some registrants have responded by diversifying across multiple TLDs, seeking resilience in redundancy. Others have gravitated toward registries with reputations for minimal intervention, though such havens are themselves subject to international scrutiny and pressure. The result is an uneven playing field where trust in the neutrality of the DNS is increasingly eroded.

The broader question is whether registries should be content moderators at all. Advocates of a purely neutral DNS argue that moderation should occur at higher layers of the stack, closer to the content itself, where competition and choice mitigate the risks of monopoly control. They warn that embedding content judgments into the DNS undermines its universality and stability. Proponents of registry intervention counter that the DNS is too central to ignore, that harmful domains inflict real damage, and that registries have a responsibility as stewards of critical infrastructure. Between these poles, the reality is that registries already moderate content, whether reluctantly or assertively, and the lines they draw are constantly shifting under external pressure.

In the coming years, the debate over registry content moderation will likely intensify. As governments adopt stricter digital policies, as advocacy groups demand accountability for online harms, and as global conflicts spill into cyberspace, registries will face escalating demands to take sides. The lines they draw will not remain static; they will move with political winds, technological shifts, and public controversies. Whether the DNS can sustain its reputation as a neutral backbone of the internet—or whether it becomes another contested battleground of digital governance—depends on how these lines are negotiated, by whom, and in whose interests. Content moderation by registries is no longer an exception but an evolving norm, and the struggle over where the lines should lie will shape the future of internet governance itself.
