All of the paedophiles registered on the pay-per-view websites between May 1999 and September last year. Every customer had to provide an e-mail address and his credit card details: by return they were sent a username and password to enable them to log on to a paedophile site. In October, detectives in the US arrested the websites' owners and seized the database.
The FBI did not generate, operate or sell anything. They shut down a site and are using it's database that goes back three years to bust pervs who purchased kiddie porn.
No intrapment here at all, just pedophiles getting caught trading money for dirty pics of kids.
