One week later, the spammer struck again, using Markley's domain. Five days after the second attack, the spammer struck yet again. Thousands of bounce reports and hate e-mails arrived in Markley's inbox. And Earthlink reps told Markley they could do nothing to help him.

Markley checked the headers on the original spam returned with some of the bounces. Then he learned how to access domain-registry information and how to use a trace-route program. Over the next two weeks, he painstakingly worked his way through a half-dozen hijacked servers and a dozen spoofed e-mail addresses and bogus identities to find "his" spammer. "Last Thursday, at around 7 p.m., I finally knew without a doubt that my nemesis was Eddy Marin, who has a reputation as the world's most prolific spammer," said Markley.
