I just loaded up my Spam trap here
Essentially when a spam harvesting robot hits my domain it will find that page and think mmm yummy look at all these email address’s! When it gets to the bottom it will find the link to page two (The desert) and merrily harvest those to. Once it gets to the bottom of page two it will use the link back to page one and voila my script will have dynamically generated a whole new set of addresses for it to munch on 🙂 Round and round it will go.
Will it stop spam? No. Will it fill up the owners database with crap? Yes. Will he think twice about sending his bot to me again? Yes.
If you want the script for your own domain send me an email and I will send it to you. Have a good weekend.
