Blog Comment Spam is Really, Really, Really Annoying

I keep getting spam from some bunch of (expletives deleted) as comments to the blog. It's all:

Nice.

Interesting.

Cool!

With some bogus URL they're trying to get people to click on, from weird psuedo-Greek names mostly ending in 'os'. They end up in my possible spam folder, and I delete them all, but I can only delete a few at a time, and if they build up for weeks, it takes a while to get them to go away.

In response to this, I've just set the blog to only allow non-anonymous comments. Hopefully, this will solve my spam problem. If it causes you problems, please send me mail and I'll think about changing it.
