Improve Age Verification for Mature Streams
I'm not a fan of the current way Twitch has it setup for Mature Streams that are marked for +18 Mature, a click of a button shouldn't just automatically grant whoever to watch those types of streams, and so what I propose is a Age Verification system to verify those users are of age before being allowed to watch those streams by using a Digital ID Age Verification system. This would not only properly protect minors and prevent them from watching stuff they shouldn't, but also adult streamers as well.
A simple age verification check would make it so that people who are allowed to watch mature content are allowed, and those who aren't are kept out, clicking a button on a stream when warned about mature content doesn't seem like enough effort, and somewhat lazy. But it should be a one-time verification thing that ties with the users account after verifying their age. And no it's not private sensitive information that will be shown or available to streamers themselves, but only by Twitch itself and the ID system who can only see this information. The ID system would also have to make checks that they're verifying a real person and not a generated bot in order to fool the system with fake information.
There are third-party ID verification systems like Passbase which can automate ID verification and age verification process.
