Return of the Japanese Spammer

The blog got hit with spam comments in Japanese on nine different posts during the night. I've deleted all of them, and if it continues I'll turn on comment moderation again. I'd rather not do that unless I have to, though. I like for people to be able to see their comments right away, and it doesn't take much longer, if any longer, to delete the spam than it does to approve comments. I do hope this isn't the start of a whole new wave of spam, though.
