[REQUEST] Automatic rotation of CAPTCHA background noise

Post by phpDummie »

Would be a spam-bot killer to automatically randomly rotate, within preset parameters, the background noise on every registration.

I don't see how it would. Spambots can either filter noise with a certain accuracy or they can't. You should decide on what is the correct balance for defeating bots versus accomodating humans and use that every single time.
