Several fellow bloggers have noticed comment spam creeping into their blogs. Comment spam is where you receive comments that advertise for Viagra or something and it is totally unrelated to your post. Fortunately, Blogger has introduced a new feature to help combat comment spam. It's called Word Verification. Word Verification shows an image on your comment entry screen and asks that the commenter enter the text from the image. The text is wavy, or slightly distorted in some way such that it can't be easily read by a program, but real people will have no problem recognizing it. It is a small extra step to make sure that your comments section don't get overrun with spam. I'll be turning it on here. If you have a blog, you might want to consider too.
