Believe it or not, this tiny, obscure blog already gets an overwhelming amount of spam comments.

I have a simple anti-spam system in place, which asks commentators  to fill in a simple arithmetic problem.  This probably does cut down on some automated spam, but imperfectly.  Finding a better wordpress anti-spam system seems to be difficult and time consuming.  Consequently, for now, all comments need to be manually approved by me before they will post.
