Word verification

Even if my Blog is not so popular I decided to add the word verification on comments.
I really like to hear comments from my few readers, but I would like to make sure the comments are not about getting a mortgage or buying Viagra.

Sorry for the little hassle, but we need this.
I want everyone to be able to comment, but I also want to avoid this. If you are a real person and not a bot you won’t have much of a problem typing the words read from the image.
