I'm not a Jessi slaughter expert, but from what I remember, it wasn't just the sex with a singer that made her famous. She was an attention whore on some YouTube-like site (90% sure it was Stickam) where she would say phrases like "I'll put my glock in your mouth and make a brain slushy" and "all you hater-bitches that are just jealous"; oh and don't forget "I like to fuck until I bleed" (she was 12 -13 at the time). She would also make super sexual videos.... at the age of 12....She started off super 'gangsta' and then couldn't handle it when whatever -chan was around at the time found her. Pretty sure ED has more of that time of her life recorded than the original post does.
Her dad got her the most attention though. His whole "you dun goofed" video went uber-viral. And then people started seeing the old Jessie Slaughter tough-guy videos that had gone unnoticed. Which made Jessie start claiming she was being bullied and she made some cry-victim videos that caught the attention of some news outlet. Nothing really came out of it after that until someone dug up that her dad was in jail for abusing the family and/or drug use.
She was banned from the Internet for a while; don't remember what she did to get the ban but she violated the ban a couple months later by getting a friend to record her "apologizing " to some people she had wronged.
