This cut a huge amount of drive-by opportunist spam. Obviously, it won't catch everything, but every filter you add raises the bar a little. | |

accessibility can by simple bypassed adding some text: Hey, if youre a human, keep this field blank!

A honeypot Captcha includes a field that is HIDDEN by CSS so only the bots (and those with IE 3.0) see it. If it's filled, it's a bot. Very easy to implement. | |
