It took him about five months to write and execute a program that could locate registered sex offenders on MySpace who were dumb enough -- or hey, maybe just that darned honest -- to sign up using their real names.
MySpace has been waiting for new laws to be passed that would require known sex offenders to register their e-mail address in addition to the other required information. This approach seems somewhat pointless considering how many e-mail addresses most people have.
I know people who have 10 or more. But who can blame MySpace for assuming that no one on the registered sex offenders list would sign up on MySpace using their real names? Still, Poulsen took a shot, and the results were astonishing.
One of the sex offenders Poulsen uncovered had been actively compiling a list of young friends and sending the underage boys sexually explicit, private messages. He has since been arrested, although police were only able to charge him with attempted child endangerment since he never successfully made physical contact with any of the young boys he was communicating with. According to Poulsen, there were several alarming communications found on the pages of other registered sex offenders, but for every one who appeared to be indulging their predilections, eight seemed to be doing just what pretty much every other MySpace member is doing: Poulsen admits that he ended up with a bunch of false positives in the program's reported matches, which he was able to weed out by comparing the MySpace profiles to the mug shots and ages included in the sex-offender database.
It's not a perfect system, but it seems to be a better plan than waiting for Congress to pass a law that would be absurdly easy to bypass in the MySpace registration process.
Who has only one e-mail address these days? Can Congress enforce a single-address rule for sex offenders? Poulsen's code will soon be released in open-source format so police departments can have full access to the program.
MySpace has not commented on the program itself. For more information on MySpace, sex-offender databases and related topics, check out the next page.
