I use a modified version DominoBlog for my blog template. As has already been stated it "runs some javascript to add an extra parameter to the http POST request". It also uses a link throttle. Set the maximum number of links that you will accept and almost all comment spam goes over your threshold and the comment will be refused. The configuration form also has the ability to require fields, which I've set to require all except the web site field.
I've added a "honey pot" field {Link} that is checked in the code that accepts the comment. If it's not right, the comment is blocked.
These measures work for all but humans. If they don't break the rules, then the comment is accepted. However in the last three and half years I've only received three or four human created comment spam messages.
I subscribe to my comment feed so that I can check for comment spam. I do have the option to moderate comments but so far haven't had to do that. After three years I set enabled the agent that automatically deletes all blocked comments as I have yet to find a valid comment in the blocked comments view. I'm so confident that there won't be a valid comment in the blocked comments view that I actually have it run every night.
I receive around 100 to 200 comment spam messages a day and over the last three and a half years 247 valid comments.
