I think that even making guesses about someone's identity on an anonymous account is in very poor taste and actively discourages participation by people who are attempting to use anonymity as a tool to, "share [their] mind authentically". I consider that sort of thing d̶o̶x̶i̶n̶g̶ similar to doxing because it takes actions on identity outside of the anonymous person's terms. These days I'm generally against anything that has the potential to decrease activity on LW. (And even if Clarity is a generally ridiculous poster, he does foster discussions on the site at the very least.)
