The girl is Jessica Leonhardt, aka Jessi Slaughter, the 2010 Internet celebrity known for her provocative videos, angry father, false accusation of rape against Blood on the Dance Floor’s lead singer -- and for all the cyberbullying she’s endured.
The Slaughter saga began in July 2010, when Slaughter’s video addressing her haters -- mostly known for the words
"If you can't stop hating...I'll pop a glock in your mouth and make a brain slushie”-- caught the attention of rancorous online community and image board 4chan and rocketed her to Internet fame.
In what Oh Internet, a site documenting online culture, describes as an attempt “to alert her parents of their child's extra-curricular activities,” 4chan engaged in multiple “raids” against the Slaughter family.
These “raids” included publishing her personal information, sending her pizza and escorts off Craigslist, prank-calling, trolling Slaughter’s social media accounts, flooding her chat rooms, and uploading mean-spirited videos to YouTube.
