Jessica Leonhardt, also known as Jessi Slaughter and formerly as KerliGirl13 (now known as Damien on her new account: shinigamikilla) on YouTube, is an 11 year old girl and fan of the band Blood on the Dance Floor whose attention-seeking online behaviors caused her to become the target of a 4chan raid, resulting in a rage-fueled and ill-advised retort from her father that became the subject of masses of image macros and videos and becoming an Internet phenomenon.
On July 10th, StickyDrama user tdomf_e8e13 posted an accusation that Blood on the Dancefloor’s Dahvie Vanity was supposedly involved with Jessi: BOTDF lead singer Dahvie Vanity is at it again! He was apparently having a “friend with benefits” type of relationship with self-proclamed “scene queen” Jessi Slaughter who is only 11! … I found this pic of the two of them at the may 2nd concert in Orlando.
…I have also talked to other people who say that they did fuck last sumer when she was 10. I cannot believe that Dahvie has sunk to this level! I don’t know whether this rumor is true, but if it is he’s disgusting! [note: bold added for emphasis]
On July 12th, Jessi posted a response on Stickydrama, denying the claims. "Muh Mom Has Read This And Is Talking To Dahvie On The Fone Right Nao! So I Would Shut Your Mouths If I Were You! I Have Muh Life And Dahvie Has His. We Are Just Friends!"
Jessi Slaughter was, at this point, something of a micro-celeb on StickyDrama, and had been posting questionable images and videos on her Myspace, YouTube, and other social networking profiles.
But one video in particular caught the attention of 4chan’s /b/:
TrollingThe effects of her videos being posted to /b/ and various Tumblr blogs led to Anonymous trolling her with taunts of her being stupid and ugly. She replied with comebacks that had little effect on the trollers.
Anonymous soon found out all of her personal information (phone number, address, Twitter, etc.) From here, the attacks escalated. The trolls managed to get her email by sending her friend requests on Facebook with unusual names like “I.P. Freely.” Despite this, Jessi continued, making a Tumblr account, posting pictures to continue taunting the trolls.
Jessi’s FatherWhen Jessi made this tearful response video, her father came into the shot, delivering an angry rant to YouTube. Unwittingly, he delivered a few phrases that soon become highly-quoted in image macros and other articles including “You done goofed,” “backtraced,” “cyberpolice,” and “consequences will never be the same.”
On August 11, Jessi's father,Gene Leonhardt, sadly passed away from a heart attack. He was 53. Jessi's mother confirmed this on her twitter.
Sometime in the afternoon of July 16, 2010, baseless rumors of “Jessi Slaughter Given PCP by Her Father” began to rise rapidly on YouTube and Google Trends. The malicious hoax was soon picked up by social bookmarking services and popular blogs, who eventually speculated 4chan users for propagating the disinformation.
