'Trusted friends' is the key term here. To become one you need to have a paid subscription and to submit a face scan or id, which is what most people here are against.

I for one will not let my child submit a face scan to Roblox in order to become a 'trusted friend', and so now they wont be able to play the games made by their friends.

subscription isn't tied to trusted friends.

age check via face scan or id for both parties is required, along with ~in-person pre-existing connections or parental permission.
