Spam Uncanned
I’ve had my first comment spam in WordPress - insidious comments that look relevant, and only the URL field is used for spam purposes. I recognized it as spam since it all came from the same IP, though the URLs varied. (I didn’t visit them.)
So I’m trying out the built-in spam blocking. In WordPress 1.2, just go to Options | Discussion and add IP addresses, URLs, or keywords to the textbox at the bottom of the page, and hit Update.
