Operation Delego
Operation Delego was a major international child pornography 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. Operation Delego is a spinoff investigation from leads developed through "Operation Nest Egg," the prosecution of another online group dedicated to sharing and disseminating child pornography. Operation Nest Egg was a spinoff investigation developed from leads related to another international investigation, "Operation Joint Hammer," which targeted transnational rings of child pornography trafficking. Dozens of law enforcement agencies were involved worldwide in Delego, including Eurojust, and arrests were made on all five continents. Twenty of those charged, however, are only known by their Internet handles, and as such were individually charged as John Does and remain at large. However, some of the indictments were unsealed as of August 2011, and the names of some of those involved in Dreamboard are publicly available. United States Department of Homeland Security Secretary Janet Napolitano stated at a news conference that  "The board may have been the vehicle for the distribution of up to 123 terabytes of child pornography, which is roughly equivalent to 16,000 DVDs," making this the DHS's largest child porn bust in its history. Launched in 2009 by federal law enforcement, Operation Delego resulted in the arrest of 52 people in 14 countries of which are Canada, Denmark, Ecuador, France, Germany, Hungary, Kenya, the Netherlands, the Philippines, Qatar, Serbia, Sweden and Switzerland, according to United States Department of Justice Attorney General Eric Holder. Furthermore, according to federal agents, while Dreamboard's servers were located in Shreveport, Louisiana, the site's top administrators were in France and Canada. Convictions 
A total of 72 individuals have been charged as a result of Operation Delego. To date, 57 of the 72 charged defendants have been arrested in the United States and abroad. 42 individuals have pleaded guilty. 25 of the 42 individuals who have pleaded guilty for their roles in the conspiracy have been sentenced to prison and have received sentences ranging between 10 years and life in prison. 15 of the 72 charged individuals remain at large and are known only by their online identities. Efforts to identify and apprehend these individuals continue. Timeline
