The spammers appear to be getting right through the multiple blocks I’ve set up. They’re getting good. As a result, I’m setting the highest level of moderation on: all comments must be approved by the administrator (me).

There’s another way to do this: there exists a plugin that will ask the commenter to look at a random image and type in the letters and numbers appearing in that image. Bots can’t generally read images (if you know of one that can, that’s one hell of an image-recognition software!), so this is more or less a failsafe. It does create an extra step for every comment, but seems to work well for some people.

Uh, comments?

Edit: Okay, this is a bad idea accessibility-wise. It is unlikely but quite possible that blind people will be reading this blog using text-to-voice software. The image option would render them unable to comment. So for the moment, I’ll moderate comments.
