One thing I have done which works really well is:

Validate the form and fail silently if any of the following are true:

1) first_name or last_name match the email regex

  - no one is named [e-mail]

2) first_name is the same as last_name

  - I'm ok with Chris Chris having trouble filling out my form.

For the "Contact Us" form I fail silently to decrease spam in our inbox.

I did this because I noticed 99.99% (made up number) of our spam matched these rules.
