CAPTCHA cannot prevent SPAM
This is a video demo on the Botmaster software that automatically posts your messages to forums, guestbooks, bulletin boards and link directories. It claims to be able to bypass every possible type of protection from automatic registration, including CAPTCHA.
For the non-techie, CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”, where a script tries to detect if the current visitor to a particular page is a bot (robot) or real human.
This is the common “type in the characters you see in the box below” text field that you find in almost any form, where the characters are distorted to make it harder for bots to decipher it.
