"Doxxing", in the original sense, involves publishing more private info, info like address, home phone, cell phone, SSN, etc. A link to someones public LinkedIn page is not a "dox."

That is an absurd definition of doxxing. Reporting the names of you have had in-person interactions with, in cases where it would not expose someone's pseudonym, is in no way, shape, or form doxxing.

I thought doxxing was the act of publishing the true identity of a person which was only known by their online handle before.
