If bots get past the captcha try changing fonts. Ideas that may be implemented in the future... 1. randomize the background with texture, color and/or gradient 2. distort the image 3. rotate the characters with different rotations. 4. use audio, svg, or flash //additional fonts can be obtained from http://simplythebest.net/fonts/ http://www.1001freefonts.com/afonts.htm //Usefull Links http://sam.zoy.org/pwntcha/ http://en.wikipedia.org/wiki/Captcha */ ?>
