I don't know if the change was intentional or not, but with the rollout of the revamped web profiles, the 18+ Verified badge was silently removed from them, and we need it back.
Many groups who offer age-gated instances, including my own, offer VRC+ verification alongside regular manual ID verification for people who have already verified themselves through VRC+. We want to offer age-gated instances without forcing users to pay up for a subscription, so doing age checks and granting a role to access specific instances was a fair middle ground.
Groups like mine rely on the Verified badge being able to be seen on the website, otherwise we won't be able to offer VRC+ as an alternative verification method and have to manually ID verify every person who wants to attend the age-gated instances. If they're already visible in-game, why not on the website too?
