All because Jessi woke up at midnight and decided to post a video on YouTube called "Haters... Piercing... StickyDrama =D".
Since then Jessi was angry that she'd been linked to a sexual relationship with Blood on the Dance floor lead singer Dahvie Vanity at the tween gossip channel StickyDrama, and she let fly at those responsible for spreading the rumours.
In one of the safer-for-work messages to her "haters", Jessi claims she'll be "poppin' a Glock in your mouth and makin' a brain slushie" and tells them all to "suck her non-existent penis".
“Suck it and get AIDS and die," she says.
Her response was not a YouTube hit by any measure, barely passing the 100,000 mark, but it was enough to attract the troublemakers on a website notorious for pranks, 4chan.
One 4chan troller - net users who specialise in baiting victims and internet hate machines - decided to take up the cause of making life hell for Jessi and her family.
The hacker on steroid's first step was to pose as a police officer and ring her mother, Dianne, claiming that the man who was the target of her daughter's "brain slushie" threat had disappeared.
From there, as Jessi's internet fame spread, Anonymous and other users began posting her personal details on the net, including her phone number and home address.
They spammed her Facebook, Twitter and MySpace accounts and had pizzas sent to her house.
And then the trollers got their prize - 11-year-old Jessi Slaughter sobbing on YouTube and a her extremely net-unsavvy father's attempts to threaten the stalkers, much to their delight.
"Ya' dun goofed!" immediately became YouTube's most popular post of the day, and introduced several choice terms such as "I've backtraced it" and "consequences will never be the same".
It now hit the two million views mark ... and Jessi Slaughter's family home is under siege.
Jessi was put under a court order not to access the internet for at least three days.
There's a criminal investigation into the video of Anonymous pretending to be a policeman.
