I've noticed a sudden upsurge of spam the last couple of days. My personal domain is getting slammed despite filters, and some are slipping through here as well. It seems to come and go in waves, but I wanted to tell people I've noticed it. I'd turn on my comment moderation, but I can't moderate comments today and don't want them clogged up and invisible. So I hate to say it, but for today and maybe tomorrow I'll have the word verification feature on. Sorry.
