Much of the advocacy around age verification discusses the privacy harms of age verification. Yet these measures also threaten something more fundamental: equal access to information and the ability to exercise the right to freedom of expression.

As governments and companies increasingly require users to prove their age before accessing online services, these individuals risk being excluded from large parts of the internet altogether.
