FBI battle against online porn by running the site

"WASHINGTON — For nearly two weeks last year, the FBI operated what it described as one of the Internet’s largest child pornography websites, allowing users to download thousands of illicit images and videos from a government site in the Washington suburbs."

"The operation — whose details remain largely secret — was at least the third time in recent years that FBI agents took control of a child pornography site but left it online in an attempt to catch users who officials said would otherwise remain hidden behind an encrypted and anonymous computer network. In each case, the FBI infected the sites with software that punctured that security, allowing agents to identify hundreds of users."

"The Justice Department acknowledged in court filings that the FBI operated the site, known as Playpen, from Feb. 20 to March 4, 2015. At the time, the site had more than 215,000 registered users and included links to more than 23,000 sexually explicit images and videos of children, including more than 9,000 files that users could download directly from the FBI. Some of the images described in court filings involved children barely old enough for kindergarten."

"That approach is a significant departure from the government’s past tactics for battling online child porn, in which agents were instructed that they should not allow images of children being sexually assaulted to become public. The Justice Department has said that children depicted in such images are harmed each time they are viewed, and once those images leave the government’s control, agents have no way to prevent them from being copied and re-copied to other parts of the internet."

"Officials acknowledged those risks, but said they had no other way to identify the people accessing the sites..."

"At some point, the government investigation becomes indistinguishable from the crime, and we should ask whether that’s OK," said Elizabeth Joh, a University of California Davis law professor who has studied undercover investigations. "What’s crazy about it is who’s making the cost/benefit analysis on this? Who decides that this is the best method of identifying these people?"
