No, that's not what doxxing is.
Journalists understand the need for anonymity in certain contexts, but like I said, it's often part of a bargain for information. It's not about letting people control stories about them. They write stories about events that are embarrassing or damaging to named individuals all the time (e.g. reporting on the police blotter), even though I'm sure all those people would have preferred their identities be kept secret.
> While doxxing as a term is particular to the internet, it - at least as a concept - predates the internet.
Doxxing is entirely particular to the internet, because IRL people typically use their real names, and almost nobody hides behind pseudonymity.
