The Thiel/Palantir backed Persona age verification platform that Roblox, Reddit and Discord use left loads of info on insecure systems.

(Edit: apparently not Discord now)

"researchers found details about the extensive surveillance Persona software performs on its users. Beyond checking their age, the software performs 269 distinct verification checks, runs facial recognition against watchlists and politically exposed persons, screens “adverse media” across 14 categories (including terrorism and espionage), and assigns risk and similarity scores.

Persona collects—and can retain for up to three years—IP addresses, browser and device fingerprints, government ID numbers, phone numbers, names, faces, plus a battery of “selfie” analytics like suspicious-entity detection, pose repeat detection, and age inconsistency checks."

@xtaldave Why not? It's had a Nazi problem for ages, so this is the standard distraction.

@xtaldave

Persona, isn't that the site on the background of LinkedIn, that does the real verification and storage of your data?

@WvOostveen I am not 100% sure, but quite possibly, yes.
@WvOostveen @xtaldave Yes, LinkedIn is using this too.
