Given that his name was already out there to the point where it's trivially discoverable, did he even have pseudonymous status to begin with? I still have to work to recover Dril's name, and I confess I never heard Infosec Taylor Swift's name. But I actually had this name in the back of my head for years now. If an NYT reported had asked me to name him, I probably could have in a heartbeat.
A lot is being said about the transgression of the press here, but if you've got a fan-run reddit where they're using your full name publicly, maybe it's somewhat futile to delete your blog and blame the NYT no matter how much your purported genius entitles you.
I am definitely one of those spooky antifa types that folks here label with derision as the "ctrl-left". If anyone wanted to somehow threaten his safety, they're a google search away. That places him closer to discoverability for most folks than any NYT article which will squat behind a paywall.
Far more likely is that few have bothered Scott or substantially transgressed his safety because he's actually a very small niche blogger with a loyal but admittedly small fan community.
I admit I'm a famously uncharitable audience for bloggers, but I'm much more inclined to think that this entire series of events is either a fit of pique that blew up in Scott's face, or a deliberate attempt to create a controversy to gain publicity.
[0]: I've been informed that as there is a central controversy over if this man is in fact anonymous, the mods are going to err on the side of caution, and so I've re-presented this post with the item redacted even though it turns out all it took to find the name was to let google autocomplete the name, populated from content 7 years old.
[1]: I've screenshotted what _I_ see when I use an incog to search for him on this tweet: [redacted], it turns out even THIS is too much of a concession to reality. My twitter account has the screenshot if you'd like to see it. But it consists of typing "scott alexander"
