You're ignoring the bits of that article you don't like:

Essentially, doxing is revealing and releasing records of an individual, which were previously private, to the public.

Where's the "reveal" in this hack? They'll use the hacked info privately or sell it.

What are you talking about? I never said this was "doxing"; I know there was no reveal. I was referring to the definition of "doxing" which I felt didn't fit.

Did you read the comments completely? If Randi, Anita, and Brianna weren't anonymous but they were "doxed" it seems to me that "doxing" doesn't have to refer to revealing info of an anonymous person.
