From February this year - Apple App store is home to multi-million dollar scams. The method the guy used to find this is so childish it's a wonder how Apple could have missed. Also Apple employs some dark patterns if you wanna report scams.
This isn't true. The phonebook we had had only Name, Phone number and very broad location. Also those days, phone number was just that - a phone number. Nowadays it's a unique identifier for lots and lots of things including government stuff. Some government stuff even uses it for authentication/authorization.
Also I guess user ID means it gives access to their fb profile page I guess? From there one can scrape pics etc (public ones).
Some might laugh this off as 'oh it's just scraping'. But I remember reading some comments in HN that there are apps that can scan faces and pull personal info including where they live, work etc. So each leak uncovers a person little by little.
This vindicates the stance taken by Signal to not even collect metadata.
Edit: I mean surreptitiously scan the face of a stranger you see in public and the app will tell you about them. Don't know names of the apps.
