BotDetect ASP CAPTCHA

BotDetect 3 ASP CAPTCHA is a website security solution (component) designed to protect your registration, comment, poll, guestbook, content submission, and other online forms from automated spam submissions. It generates CAPTCHA images with textual code rendered in them that are easily decipherable to humans -- but not to spam bots.
In essence, it allows you to focus on your code or content -- instead of on deleting spam.
