A briefing paper from the European Parliamentary Research Service has raised the prospect of age verification requirements being extended to virtual private networks - a move that would mark a significant escalation in Europe's effort to restrict minors' access to online pornography. The two-page document, promoted by the service on social media this week, frames the growing use of VPNs to bypass regional age-verification laws as a regulatory gap that may require a legislative response. For privacy advocates, the framing itself is the warning sign.
