If you’ve read online offers peddling any number of ‘enhancing’ pills, NBA swag or opportunities to purchase only the most affordable iPads online whilst perusing a forum or the comments section of a blog, then the purveyor of said website is probably in need of some measure of controling spam. The common go-to controls for such precautionary measures are called CAPTCHA, or their adorable little brother SAPTCHA.
CAPTCHA is an absurd acronym for “Completely Automated Public Turing Test To Tell Computers and Humans Apart” and in its essence is a humanity test; kind of like the one administered in the 1982 movie Blade Runner, but with considerably less suspense. The hope behind CAPTCHA is to stymie a spambot by confounding it with a question or task that rudimentary bot software can’t figure out, but is still something a human with fully-functional fuzzy logic can solve easily.
