Honeypot For Identifying Email-Harvesters
Cheese Man writes "Mark Pilgrim describes a simple way to identify email-harvesters: "In each page I serve, I include a bogus email address, encoded with the date of access as well as the host IP address ... This has allowed me to trace spam back to specific hosts and/or robots." There's even a simple one-line example done with PHP. (Thanks to BoingBoing for the links.)"

2) WHOIS them
3) Send E-Mail saying "give me $1000 or I sign you up to every known spam list and catalog order on the planet"
4) ???
5) Profit!
