I'm in the UK and discord has asked me to complete this check (but I haven't, yet). I can still use discord just fine, it just won't let me view any media it considers "adult".

I am an adult but refuse to let them scan my face as a matter of principle, so I've considered using https://github.com/hacksider/Deep-Live-Cam to "deepfake" myself and perform the verification while wearing a fake face. If it works, I'll write about it.
