Best way how to stop automated abuse is using php generated images,
similiar which yahoo uses to prevent automated sign-ups. Users then must
write down the control number/string for each submit and you compare if
the submited control numer corresponds to the one you have generated
before processing user input. PHP has functions to work with images like
imagettftext etc. Good luck.
