> He's published his full name multiple times (even on his own blog).
I'm almost certain this is untrue. Are you possibly mistaking his pseudonym "Scott Alexander" for this full name? If not, and you understand that Scott and Alexander are his first and middle names, could you please provide a link to an example of where he has published his last name on his blog (or at this point, on the relevant archive.org page)?
Edit: I'm guessing from your comments further down the page that you understand the pseudonym aspect, and have a different conception of "publish" than I do. Do you perhaps mean that he linked or referred to a scientific paper on which he was listed by full name as author? If so, and if true, the strongest I'd probably phrase this is "revealed" rather than "published". If not, and if I'm wrong, and he has directly published his last name on his blog in a manner intended to make it publicly known, I'd like to know so I stop making false claims in the future.
