Many of the messages Carlson is accused of sending were obscene and scatological; one of tamer ones said “Corrupt Philly Mafia Keeps Phils in Cellar.”

October 7, 2003 - PHILADELPHIA – United States Attorney Patrick L. Meehan today announced the unsealing of an indictment returned on September 25, 2003, against ALLAN ERIC CARLSON. Agents of the Federal Bureau of Investigation arrested Carlson this morning at his residence. Carlson is charged with \"hacking\" into computers around the country, hijacking or \"spoofing\" the return addresses of e-mail accounts of reporters at the Philadelphia Inquirer and the Philadelphia Daily News and e-mail accounts at the Philadelphia Phillies, and launching spam e-mail attacks. He is also charged with identity theft for illegally using the e-mail addresses of the reporters.

The indictment charges that Carlson, a disgruntled Philadelphia Phillies fan, hacked into computers of unsuspecting users and from those computers launched spam e-mail attacks with long messages voicing his complaints about the Phillies management. The indictment charges that when launching the spam e-mails, Carlson's list of addressees included numerous bad addresses. When those e-mails arrived at their destinations, the indictment charges that they were \"returned\" or \"bounced\" back to the person who purportedly sent them – the persons whose e-mail addresses had been \"spoofed\" or hijacked. This caused floods of thousands of e-mails into these accounts in a very short period of time.
