Trolls posted Scott Alexander's real name in many places after he tried to protect his anonymity.

True if evidence shows that, after Scott Alexander publicly tried to protect his anonymity (around June 2020, when the NYT story was pending and he took down SSC), people posted his real name in many places such as forums, social media and comment sections. Mostly true if his name was spread widely but the posters were not mainly trolls, or the timing differed slightly. Mixed if his name was posted only in a handful of places. Mostly false if his name was rarely posted and the spread mostly came from other sources (for example it was already widely known). False if the evidence shows his real name was not posted publicly by others during that period.

   “But so far most people who google my real name don't find my blog. People who do the opposite can find my real name with a little Internet savviness and a minute or two, and maybe the extra difficulty just makes me feel more secure without really keeping me any safer.”

   “Last week, Scott Alexander, the author of the influential rationalist blog Slate Star Codex (SSC), abruptly shut down (perhaps temporarily) his blog in advance of a New York Times (NYT) story on him and SSC that would include his real name.”

   “And now that I’ve publicly admitted privacy is important to me – something I tried to avoid coming on too strong about before, for exactly this reason – some people have taken it upon themselves to post my real name all over Twitter in order to harass me.”

   “His pseudonym is not watertight; I once worked out his real name from clues on his blog, which I admit is a mildly creepy thing to do. Some other people did the same, but not out of passive interest:”

    “Even the online groups who hate him most have refrained from publicly naming him in the past.”

11. E11 Why is the New York Times threatening to reveal blogger Scott Alexander’s true identity? New Statesman · 26 June 2020

    “It took me about 30 minutes, and for many it won’t take more than five.”

The only direct support for people posting Alexander's real name widely after June 2020 is his own blog post, which says people posted it "all over Twitter" to harass him (E8). That is an ordinary statement by the subject, not independent confirmation. The independent sources say his pseudonym could be worked out and that hostile groups had held back from naming him in the past (E9, E10, E11). A February 2021 New Statesman column says his real name is now in the public domain and that "the article" revealed it (E1, E2). None of these independently shows trolls spreading his name widely between June 2020 and January 2021, so the evidence does not settle the claim.
