I mean, if someone goes by a certain identity online when running a blog or working on something, what's wrong with just using that name in an article or video about them? Whenever I interview a game developer that uses a pseudonym, or a YouTuber/Twitch streamer/blogger in the same situation, that's the name I use in the article. I might ask them for a bit of background info at one point sure, but I won't push for it, nor will I go around trying to dox them to get said information.
Is there any real reason that 'Scott Alexander [last name]' would be used rather than just 'Scott Alexander'?
Still, it's nice to see the blog's back up, and I hope people learn from this debacle in some way or another.
