Well I finally had to verify my age in Bluesky, after receiving a direct message I couldn't open until I did so. The two options were: 1) face scan, or 2) via credit card. There's no way I want to do a face scan (ref Sam Altman's dystopian The Orb!). But I actually don't mind the credit card method, because I use that across the internet anyway.

Also, I support the UK government's effort to try and prevent underage people from accessing 18+ content (I have kids!). Bluesky process is fine.
