Computer Scientists Caution Against Internet Age-Verification Mandates

Background

Effective January 1 2027, providers of computer operating systems in California will be required to implement age verification. This is part of a broader wave of state and national laws aimed at limiting children’s access to potentially risky content. Over 400 computer scientists have signed an open letter warning that the rush to protect children from online dangers may introduce new risks, including censorship, centralized power, and loss of privacy.

Concerns Raised

Influence Over Content

The scientists note that those deciding which age‑based controls exist—and those enforcing them—gain a tremendous influence over what content is accessible to whom on the internet. This influence could be used to censor information and prevent users from accessing services.

Impact on Privacy and VPN Use

Regulating the use of VPNs, or subjecting them to age‑assurance controls, would reduce users’ ability to defend their privacy online. It would force regular users to leave a larger footprint on the network and leave at‑risk populations—such as journalists, activists, or domestic‑abuse victims—unprotected. The letter argues that trying to regulate VPN use for non‑compliant users would be no more effective than attempting to forbid end‑to‑end encrypted communication for criminals. Secure cryptography is widely available and cannot be “put back into a box.”

De‑platforming and Migration

If minors or adults are de‑platformed via age‑related bans, they are likely to migrate to fringe sites that escape regulation. Since the main platforms would all be regulated, users may seek similar services outside the regulated ecosystem.

Data Collection and Privacy Risks

Implementing age verification requires collecting extensive data on everyone to restrict the activities of minors. This increases the risk of data abuse and privacy breaches. For example, a breach exposed government ID photos of 70 000 Discord users who had appealed age‑assessment errors — details here.

Recommendations

Instead of mandated age restrictions, the open letter urges lawmakers to:

• Regulate social‑media algorithms rather than imposing blanket age verification.
• Support parents in locally preventing access to non‑age‑appropriate content or apps, without requiring service providers to implement age‑based controls.

These approaches aim to protect children while avoiding the unintended consequences of broad age‑verification mandates.
