On September 9–10, 2026, Australian Steam users began reporting that Valve had switched on proof-of-age verification for R18+ rated games — and that the only accepted proof is an active Australian credit card. Users attempting to open the store page for a mature-rated title are met with a message citing the Age-Restricted Material App Distribution Services Code and instructing them to "add a valid Australian credit card to your account and afterwards update the Mature Content Preferences." According to reporting by IGN on September 10 and Game Developer the same day, debit cards, PayPal, passports and local ID are not accepted, and the card reportedly must remain active on the account even if the user never spends through it.

Why It Matters

This is the age-verification debate arriving at the payment rail, which is precisely where the pleasure and adult-content industries have always been most vulnerable. When a platform elects to satisfy an age mandate by demanding a credit card, it quietly converts an identity question into a creditworthiness question — and creditworthiness is unevenly distributed by age, income and immigration status. The young adults most likely to be excluded are the same demographic that adult and sexual-wellness brands rely on for growth. It also previews a compliance pattern worth watching. Regulators in the UK, Australia, Ireland and a dozen US states are all converging on age assurance, but none of them mandate *how* to do it. Left to choose, a platform with no appetite for handling identity documents will reach for the cheapest signal it already has — the card on file. Expect sexual-wellness retailers and connected-device app stores facing similar mandates to reach for the same lever, with the same exclusionary side effects. For anyone building age-gated commerce in this sector, Valve just ran the experiment in public: the cheapest compliance option is also the one that alienates your customers fastest.

The underlying legal requirement is not new. Australia's online safety codes covering age-restricted material took effect in March 2026, extending the framework that already banned under-16s from major social platforms. What is new is Valve's implementation — and its choice of the narrowest possible verification method. IGN's Luke Reilly noted that rival platforms PlayStation and Xbox offer multiple verification routes, and that Valve's approach lands badly in a market where credit card ownership has fallen sharply: roughly half of Australian consumers hold a credit card at all, and only around a quarter of those aged 18 to 24 do. Both IGN and Game Developer said they had contacted Valve for comment.

The practical effect is a de facto adults-only gate that locks out a large share of actual adults. Reports collected on Reddit and summarized by Game Developer describe users unable to even browse an R18+ store page — the restriction bites at discovery, not just at checkout. Some users reported certain debit cards slipping through, suggesting the check is really a card-network BIN lookup rather than a purpose-built identity system. Others pointed out the absurdity of decades-old Steam accounts being asked to prove adulthood.

For the sexual technology beat, this matters because Steam is not a porn site — it is a mainstream commerce platform that happens to carry adult-rated interactive content, including a substantial catalogue of explicitly sexual games that has grown since Valve loosened its adult-content rules. Age-assurance regimes written with Pornhub in mind are now reaching general-purpose storefronts, and the compliance path platforms choose is being set by cost and convenience rather than by accessibility.
