My guess would be that that is a convenient Schelling point. (Edit: And not exactly a Schelling point but there seems to be some history on the internet of it being more acceptable to post methods than results that lead to privacy issues.) It makes it so that there’s still a barrier to get the information but limits that so that someone still needs to do the work. Moreover, it only goes in one direction. That is, it allows someone here to get the prof’s name but it doesn’t make it easier for someone else who already knows the prof’s name to find the blog.
