Playpen
Playpen was a child pornography website that operated through the Tor network from August 2014 to March 2015. After running the website for 6 months, the owner was arrested by the FBI. When it was shut down in March 2015, the site reportedly had more than 215,000 users and contained about 23,000 sexually explicit images and videos of children, including toddlers.[1] Controversially, after their arrests the FBI continued to operate the site for an additional 13 days as part of "Operation Pacifier."
