Wisconsin Gov. Tony Evers vetoed a bill that would’ve required residents to verify their age before accessing porn sites, as reported earlier by 404 Media. In a letter to the members of the assembly last week, Evers writes that the bill “imposes an intrusive burden on adults who are trying to access constitutionally protected materials.”

The bill (AB 105) would’ve required sites with more than one-third of their total content deemed harmful to minors to impose a “reasonable” form of age verification, such as asking users to show their government-issued ID. More than two dozen states have already passed similar age check requirements for access to adult content, including Arizona, Florida, Georgia, Missouri, Texas, and Virginia. As a result, Pornhub has blocked its site in these locations.

Last month, the Wisconsin American Civil Liberties Union testified that AB 105 “raises significant concerns around privacy, surveillance, and the First Amendment,” and it seems like Evers agreed. “I am vetoing this bill in its entirety because I object to this bill’s intrusion into the personal privacy of Wisconsin residents,” Evers writes, adding that he’s “concerned about data security and the potential for misuse of personally identifiable information” obtained as a result of the age verification process.

An early version of Wisconsin’s age verification bill also included a ban on virtual private networks (VPN), which people have been using to circumvent online age checks. Lawmakers dropped this provision in February, though VPNs are becoming a target for regulators around the globe.

Despite vetoing this bill, Evers is leaving the door open for other kinds of age verification solutions, such as “device-based” methods that would verify the age of users on their phone or computer.
