Here is the explanation for it taken directly from Blogger's help files:
What is the word verification option?
The "word verification" option can be found on the Settings Comments tab for your blog.
If you choose "yes" for this setting, then people leaving comments on your blog will be required to complete a word verification step.
What this does is to prevent automated systems from adding comments to your blog, since it takes a human being to read the word and pass this step. If you've ever received a comment that looked like an advertisement or a random link to an unrelated site, then you've encountered comment spam. A lot of this is done automatically by software which can't pass the word verification, so enabling this option is a good way to prevent many such unwanted comments.

ReplyDeleteThat's wonderful. I think that if you have a lot of spam that that is a great option.
