BOTCHA is a highly configurable non-CAPTCHA spam protection framework.
In CAPTCHA, user has to prove he/she is human. Unfortunately, spambots learned
to bypass CAPTCHA really well, and real users are frustrated with increasing
complexity and burden of CAPTCHA.
In BOTCHA, we don't abuse our human users - BOTCHA protection is completely
transparent to them and non-intrusive.
BOTCHA lets spambots to prove they are bots, and let real users zip by.
BOTCHA is useful for any form that has to be protected from spambots.
