Word Verification

This morning someone mentioned the word verification on my Comments area. And to be truthful I had forgotten I had clicked that option. So I went to Help and read about it. This is what it said:

- - - - - -Word Verification prevent automated systems from adding comments to your blog, since it takes a human being to read the word and pas this step. If you've ever received a comment that looked like an advertisement or a random link to an unrelated site, them you've encountered comment spam. A lot of this is done automatically by software which can't pass the word verification test, so enabling this option is a good way to prevent many such unwanted comments. - - - - -

I've seen blog comments that have included numerous commercial ads among the comments - not a pretty sight.

So, Commenters, that's the reason behind the Word Verification.
