not used either but I have implemented just 2 of the items in
http://webaim.org/blog/spam_free_accessible_forms/ and cut spam to zero
whilst maintaining genuine submissions.

one thing I notice from CFFormProtect is

"-Hidden form field--Most spam bots just fill out all form fields and submit
> them. This test uses a form field that is hidden by CSS, and tests to make
> sure that field is empty. If a blind person's screen reader sees this hidden
> field, there is a field label telling them not to fill it out."

...true, but this does not help with auto-form-fill-assistants (discussed in
more detail on the link at the top of my mail) which are growing in
