An anonymous reader writes, "Wired News editor and former hacker Kevin Poulsen wrote a
1,000-line Perl script that checked MySpace for registered sex offenders. Sifting through the results, he manually confirmed over 700 offenders, including a serial child molester in New York actively trying to hook up with underage boys on the site, and who has now been arrested as a result. MySpace told Congress last June that it didn't have this capability."
Wired News says they will publish Poulsen's code under an open-source license later this week.
