Why CAPTCHA?

Why CAPTCHA?

In a few words CAPTCHA is a necessary evil in the computing environment to help combat SPAM. It is an acronym for “Completely Automated Public Turing Test to tell Computers and Humans Apart”. Some computer programs crawl the web trying to expoit websites that allow the posting of content by generating posts containing obscene material or advertisements. WEB2.0 websites are vulnerable to these attacks and CAPTCHA’s tend to be effective! So next time you get frustrated when trying to figure out the text on the CAPTCHA image… think twice!
