@GerardThornley@hachyderm.io @nina_kali_nina@tech.lgbt the implementation they were using at the time of posting that is the k-id system as developed by OpenAge (and you can see reference to this in the source linked from https://age-verifier.kibty.town/). I haven't done an in-depth analysis of how that system worked but the blurb on its page _looked_ reasonable (but absolutely still pending analysis) discord is switching to Persona "because bypasses" (per a Taylor Lorenz tweet/skeet, didn't see article alongside it)
