Totally agree with this.  On sites where I'm getting contact form spam I've
started doing this, with a 100% success rate in blocking spam (and presumably
a 0% rate of blocking non-spam, but even if it's > 0%, it's only going to
block people running browsers that don't support CSS, and that can't read
simple instructions, so no great loss...):

- Add txtUrl input box
- Add label saying "leave this box blank or I will ignore your message"
- Add CSS to hide both input and label
- When form is submitted, prepend POSSIBLE_CONTACT_SPAM to subject line if an
Url was entered
- Setup mail filter to file away messages with that string

Like I said works great, and doesn't annoy anybody.  It's obviously easily
circumvented, but until it is, I'm not going to worry about CAPTCHAs.
