CAPTCHA

A CAPTCHA or Captcha is a type of challenge-response test used in computing to ensure that the response is not generated by a computer, by displaying distorted images of letters and numbers. This was placed on the forum to slow down botters.

Though Captcha has turned into a bit of an amusing pass time for some Gaians. Finding captcha images that display certain words, screen capping it and then posting the results in the forums or displaying their find in signatures.
