The company that Discord uses lists the methods they accept above. Notably, they do not accept any privacy-protecting digital identity standards from US or EU citizens; they only implement national ID verifications where they receive a full birthdate, with the sole exception of AU where they allow banks to attest to age-majority.
Leveraging this press to highlight their clear desire-for / dependency-on being provided an explicit birthdate, rather than simply a bool backed by the government, would be an effective lever to pull through e.g. New York and California governmental privacy efforts — especially if one somehow got them classified as a data broker in California and therefore bound to a much more expensive set of laws, due to their insistence on being provided PII when more privacy-protecting alternatives are available there.
Yes, this isn’t a scorched earth response. Every other thread of discussion here has that covered already and I have nothing new to add there. But for anyone looking to force privacy into the budding age checks verification market at an early stage rather than trying to shut it down, here’s your roadmap to effecting real change on the matter. Good luck.
