I use Browscap [http://garetjax.info/projects/browscap/] to determine whether my forms pages are accessed by robots (using the 'crawler' entry) and display a message instead of a form. I also log those attempts to see if I mistakenly block human users.

I am not sure if relying on browscap to determine whether an user is actually a robot, because robots usually spoof the user agent information.

Anyway, logging is also an helpful practice that can be used to detect anomalous activity.
