Proving that I ain't a Robot

Many blog authors use Comment Moderation as a means of avoiding SPAM. I do this myself. If comment moderation is enabled on a blog, then one needs to type in two random words produced by an engine, to prove that the commentator is not a robot. This is a fine idea, except when it comes to how crazy some of these words are to figure out.

I notice that it is getting harder and harder to read and decipher the words that need to be typed in the box, such as the one pictured below, to prove that one is not a robot.

Please prove you're not a robot

Blogger ----> are you reading this one? Please make it somewhat easy to read the words, which we need to reproduce in the box, before our comments are published. We are not illiterate, but it is hard to read letters that are atop each other. Thank you!

Paz :)
