I like this too, particularly the second item of hidden form field that bots
just cannot resist ;).

We've implemented something similar to the timestamp approach, but instead
vary the form field name/id. Seems like the bots read a form and then
provide the names to a second process to submit. That second process is not
going to see the same form name, so the validation fails. When we combined
this with a policy checkbox ("I agree not to mis-use this resource..." or
whatever), our spam submittals dropped to zero.
