Aha!

I've just come across, on an online discussion of this sort of spam,
what sounds like a truly brilliant idea for authors of Web forms:

   The best solution we found to spam contacts is to have an invisible
   field called 'email'. If it's filled, then it's spam, and ignored. We
   haven't received a single spam contact on any of our sites since
   implementing this.
