Thanks, that should work.
The idea is to have a field hidden with CSS named something common. The
HTML can still be seen by bots and they will automatically fill it in with
junk. People won't see the field so they will leave it empty. Bots will
fill it in and the form will be rejected.
On a related note, is it possible to make the form silently fail if this
one field does not pass validation but other fields will still properly
produce error message if they fail validation?
