Comment Moderation @ Blogger

Looks like blogger has recently introduced Comment Moderation. Now you can delete the spam before it posts to your blog, rather than after. The move was announced in Blogger Buzz, and the nuts & bolts are in a Help Article.

Still this does not mean that you have blocked spam-commenters by default, but an option that stops their stuff from being published in your blog and going public. A thumbs up for Blogger for this great stuff.

So, now atleast you can stop spam-commenters to publish their comments in your blog by just using the Comment Moderation tool.
