[...] Yoti automatically flags [...] any devices running GrapheneOS. These instances are automatically reported both to the authorities and our security team.

As I misread the title: the issue doesn't involve any GrapheneOS-specific age verification. It's about a 3rd party verification provider flagging all GraphreneOS users automatically, if you do age verification for other purposes (the reported case was about PlayStation).

It was originally posted in Reddit r/privacy, where it was deleted by mods.

So does it those mean Graphene needs to label itself differently to networks?
