Posting a pseudonymous person’s name and address divulges private information: the real person behind the pseudonym. Posting a public official’s name and address isn’t doxxing.
Here's Reddit's definition:
"Doxxing is where a user publishes private or identifying information about (a particular individual) on the Internet, typically with malicious intent." [1]
Twitter's:
"Sharing someone’s private information online without their permission, sometimes called doxxing, is a breach of their privacy and of the Twitter Rules." [2]
And Wikipedia's:
"Doxing or doxxing is the act of publicly revealing previously private personal information about an individual or organization, usually through the Internet" [3]

> publishes private or identifying information
"Identifying information" refers to revealing the true identity of a pseudonymous user on the site (e.g., violentacrez), or a person who has no previous association with the site (e.g., Sunil Tripathi). In these cases the perpetrators used information that was known only to them, or that the "public" had no easy access to, or that the "public" didn't even know existed until the perpetrators brought it to their attention.
Regardless of your definition of public, the word doxxing has never covered it. We have plenty of other language to refer to the sharing of publicly available information. The word doxxing was coined to give a name to a type of invasion of privacy that came to prominence with the rise of the Internet. If you want doxxing to just mean gossip, then your word no longer has a useful and distinct meaning.
‘While doxers sometimes use hacking or deception to uncover personal details about their targets, contrary to popular belief “most of the info is public,” according to one researcher who has spent years studying and participating in the practice of doxing.’ — https://www.dailydot.com/debug/dox-doxing-protection-how-to/
The vast majority of doxxing does not require unauthorized access, social engineering or betrayal by an affiliated person. Instead, it’s almost always connecting dots between openly available bits of information and then packaging that information so as to direct and simplify harassment.
You can make the case that this data should be private, and I might agree, but that doesn't change the fact that it is currently public, hence there is nothing to be "revealed" or "doxxed". The information is already out there, in public, easy to find.
Also, doxxing isn’t illegal, although harassment is.
It is against Facebook's rules.
