Moderation temporarily turned on for comments

Spammers are currently assaulting my blog with a lot of comment spam.  I've deleted it all (I hope).  I'm sorry to say I must turn on comment moderation until these cretins go away.

I've noticed a significant surge in the last few months of comment spammers who are clearly real people rather than bots.  They write something that looks relevant to the post, in the hope that I won't notice them, and then include a link to their crappy, virus-ridden sink hole of a web site.  Since they're real people, none of the usual anti-spam systems block them.

I really, really, don't want to turn moderation on, because I know many people don't like it.  But alas I must; the only alternative is to turn off comments entirely.  Please bear with me and we'll see what happens.
