I wrote a while ago about the problem of Spam on Web Logs. In essence, I really hate Spam but didn't want to ban anonymous comments. I prefer to know who is commenting but I don't want to mandate it. Fortunately a new feature of www.blogger.com has come to my rescue. The new Word Verification feature simply asks a commenter to type in a word that is displayed as a picture cunningly foiling automated Spam agents.
So if you have a Web Log hosted on Blogger then go into settings, then comments and select Show Word Verification to banish this scourge. I'm now off to try and post a comment to see if it actually works.
