Anthony Stancl, then 17, used facebook and posed as a girl to get classmates, ages 15 to 17, to handover nude photos of themselves. He then used the photos and the threat of publicizing them to get them to have sex with him. Stancl was sentenced to 15 years in prison primarily for being a gay man.

Los Angeles Times included a video in their article. The Milwaukee Journal Sentinel's article has a more comprehensive article of the court proceeding and background information.
