This is a legitimate topic of conversation. "No doxxing" rules (and said enforcement) are really a measure of the forum. Is publicly available information 'dox'? Ostensibly yes, but where do you draw the line? Sometimes its hard to say. If someone goes around with a pseudonym all the time, but then files legal papers, are you forbidden from talking about or linking to the documents because it has that person real name and other public info on it? Does it mean you can no longer reference the public record?
Restriction on doxxing appear to exist for the purpose of preventing overly lazy persons from acting badly. However, as above, once you even talk about the existence of a document in the public record all it takes is to be slightly less lazy to find information. How far do you go? You cannot stop bad actors from acting badly.
