a captcha a day keeps the spam0r away.


“A CAPTCHA (an acronym for “completely automated public Turing test to tell computers and humans apart”, trademarked by Carnegie Mellon University) is a type of challenge-response test used in computing to determine whether or not the user is human.”

This technology is mainly used to filter all those spammers from the normal commenting users. Schrankmonster even uses this technology. Kiesow doesn’t like very long captchas and I don’t like dumb ones…like this one which was sent in by Tomasz Naumowicz:
