In the comments of this question, the poster gave what he seems to think is the real name of one of our moderators. Personally, I'm not terribly well hidden here, but pseudonyms are allowable, and doxxing feels like something chilling to the free exchange of ideas, and in the context of the discussion, feels like it was intended to be something of a threat.
Should there be a policy on behavior like that?
UPDATE: the question has been removed.
