Is there any data on what kind of hits to enrollment were taken by facebook, gmail etc when they added requirements like a phone #? Maybe it's buried in their sec filings. Anyway, this "cat and mouse" game is probably irrelevant. They're not looking for and don't need a perfect system. Bc 99% of the public couldn't care less about handing over their information.

I think you massively overestimate how many people actually care.

My guess is that 95% or more of all Discord users do not care and simply upload their selfie or ID card and be done with it. I know I will (although they did say that they expect 80%+ to not require verification since they can somehow infer their age from other parameters)
