Hm, when attempting it I get redirected to https://age-verifier.kibty.town/webview?url=null, which says:

{"error":"error parsing webview url"}

Edit: Apparently my discord account is in some kind of A/B feature test that uses a different verification provider, Persona

Persona is the same company oftentimes used for the "show your ID to get in the bar and also we'll data harvest you... and share your data with various people if asked". Go ahead and google search on them for more insight.

Hopefully your comment gets pushed to the top. Would like the security guys from the blog to see it.
