It has been brought to my attention that spammers have recently found a way to post comment spam on Blogger blogs without it notifying me via email. How they're doing it, I have no idea. I just cleaned off a bunch of them from General Comments and Smileys, which they seem to like for some reason. If you see more anywhere, please tell me.
To cut down on this nonsense, I've turned on captchas (which I typically hate with a passion), and all comments on posts over 30 days old now go into moderation. Hopefully that'll help. And hopefully I'll be able to turn off the captchas again at some future date.
