Try making a graphic on the fly with a special code word in it that they have to enter. When you generate the code word, store it in a server-side session variable which is used to compare the user's input when the form is posted.
Deform the graphic as much as possible so that OCR algorithms will fail. Voila!

They use an http get or post from an end users machine so it's impossible to tell the software apart from any other user. Has anyone here any advice on what methods to use to defeat this sort of thing?
