Stopping Comment Spam
Rather than bother the bulk of Thanet's bloggers for whom the article will possibly be a little too technical I will post a link to it on a blog I maintain exactly for all that technical stuff: How to beat blog spammers and their spam - a guide is the article (it came to six pages in my word processor while I was spell checking it) and it covers the story of what I have done and an in depth listing of things you can do too to stop spam hitting your comments.
For those on fully hosted solutions (blogger) you will have to hope that your hosts have some answers.
