Posted by Kromey at 9:05pm Jul 17 '08Anyone who's ever put up a forum has had to deal with the inevitable horde of spam-bots trying to overrun your defense. (Four, I know you know what I'm talking about!)
The image-based CAPTCHAs have become so ubiquitous now that bots can even defeat that, our last line of defense!
Well, no longer! Here's a CAPTCHA technique that's sure to foil those bots!! I'll try to implement something like this in PHP in the near future, see what kind of success I have.
