I have been reading Slate Star Codex for a long time and consider it a source of many great texts, but i do not really get this step from Scott Alexander.

Term 'doxxing' is a loaded term that may describe both revealing private information and revealing personal information researchable from public sources. While the former is condemnable, the later is more neutral and part of basic journalist work, especially if the exposed is a public persona.

Seems to me that for impartial third person it would look like a reporter wrote a neutral article about SSC mentioning authors name, SSC author overreacted and punished himself and its readers by removing the blog, and by Streissand effect much more people would know autors name now.
