“Yes, I AM a robot; you got a problem with that, buster?”

~ Tom Servo on CAPTCHA

A CAPTCHA (acronym for Completely Automated Private Turing-test to tell Computers and Robots Humans Apart) is a system used to stop people from buying hundreds of Amazon elements that clutter up some space, set up thousands of accounts in mere seconds, posting thousands of comments, etc. Here is the proof (see video) for this fact:

It takes the average human approximately 10 seconds to solve a CAPTCHA; the average human spammer somewhat longer. The average robot, however, becomes completely befuddled by this clever stratagem and will harmlessly walk away in utter humiliation.


Before you read any further, prove to us that you're a robot human by clicking on every flag and going back to this page whose associated country is in North America.

If so: Congratulations, you're a human! You can continue reading! If not: you're a robot! You cannot read the rest of the page because the rest is fully protected to administrators, the only people that can hack answer CAPTCHAs (see Uncyclopedia's protection policy). This window will automatically close and you and your robotic pals will become banned from Uncyclopedia for life.

Okay, you can relax now[edit]

Ok, so, you are an a administrator human? Whew, that's a relief. Let's move further.

The vast majority of CAPTCHA images are distorted letters with stray lines that cannot be read by robots, unlike clear text. Audio CAPTCHAs contain repeated echoing audio in different sine wave frequencies. Robots cannot hear them as regular characters because they repeat.

Mathematical CAPTCHAS, on the other hand, work on the completely opposite principle by displaying large semiprimes which no robot can resist factorizing within seconds (sort of like mouse bait).
