Operation Delego is a major international law enforcement investigation launched in 2009, which dismantled an international pedophile ring that operated an invitation-only Internet site named Dreamboard which featured incentives for images of the violent sexual abuse of young children under twelve, including infants. Only 72 charges were filed against the approximately 600 members of Dreamboard due to the extensive encryption involved. Members were required to upload new material at least every 50 days to maintain their access and remain in good standing.
