Reporting of child pornography images on Wikimedia Commons

On April 7, 2010, Larry Sanger, co-founder of Wikipedia, sent a letter to the U.S. Federal Bureau of Investigation (FBI) stating that Wikimedia Commons was hosting child pornography, contrary to Title 18 of the United States Code. His accusations focused on images in the "lolicon" and "pedophilia" categories, the latter of which contained explicit drawings of sexual acts between adults and children by French artist Martin van Maële (1863–1926).
