I really like the squiggly-letter challenge that Blogger has made available in the comments section, but with regret I must say that I can see a way in which people who operate spam bots can defeat the system. I think perhaps my sometime commenter 'ALife' can see it too. The good news is that it would still require ingenuity and human labor. The most elegant thing is that you could use the same type of system to defeat the Blogger system. Ahem, enough said. If you have any comments on this post, please email them rather than posting them. I don't want to help the terrorists.
