So the author copied data from one Microsoft site (LinkedIn) to another Microsoft site (GitHub).
Both sites use PII to target people and companies: how many annoying emails have you received from LinkedIn this week? And I mean the creepy ones, suggesting contacts based on minute details from your profile, or encouraging you to import all your contacts so they can be spammed?
But I guess if a user does it, it’s doxxing. I wonder if this is political, or maybe Medium and GitHub are just trying to avoid a potential fight with a federal agency.
