There was a brief window where you could submit fake biometrics through a third-party site to verify age on Discord, pretty sure I got the link from hackernews.
That made me feel better that Discord didn't need to store my ID or video of my face, and was only storing the results of some analysis and not the inputs.
When the social media ban went into effect in Australia last year, kids were submitting photos of their parents and dogs to get around the verification. Not sure how better or worse they've gotten, but the old adage of trying to keep things from kids only motivates them more to get around the limitations you put up.
