My understanding about CAPTCHA is just a "Turing test to tell Computers and Humans Apart." - it's an Anti-spam designed to keep your website safe from robots, these are automated programs a.k.a. bots and scripts that pretend to act like a human.

Their common manifestations come in as spam comments which we can read and tell easily. If ever these spams have any malicious intent apart from filling up our comment spaces, that may not be known immediately.

We must give credit to the CAPTCHA team who has to continuously work hard to combat the spam scourge. CAPTCHA has released a more advanced version, namely reCAPTCHA is posing a bigger challenge to users who must first answer the more difficult challenge question correctly before they are allowed to submit their comments or filled-up forms.

On the dark side, the spam artists are deploying Artificial Intelligence(AI) technology to decipher the most difficult CAPTCHA code or image(may even be illegible to an intelligent human) with unprecedented accuracy. It follows that the usual CAPTCHA's Turing test and its variants are no longer dependable.

To combat the above AI robots as well as to provide ease-of-use, CAPTCHA has now reinvented itself with a more sophisticated reCAPTCHA. It does away the need for users to decipher complex CAPTCHA code or image, they just have to click to prove that they are "not a robot".

If you have already installed more than ten plugins in your website, adding a reCAPTCHA plugin will likely zap away your web performance. While No CAPTCHA reCAPTHA may "Stop scam.Read books" (reCAPTCHA's punch line) and helps you to attract more website comments and responses, for the average website owners, I have a simpler solution for you...

Here you go: "Bye! Captcha"
