Dahvie Vanity (real name: Jesus David Torres) is one half of the "musical" duo that is Blood on the Dance Floor. The band is notoriously shitty and it's widely believed Dahvie only created BotDF so he'd have access to little girls.
Accusations against Dahvie of rape and inappropriate sexual conduct with fans has been going on for years now. His most famous victim was Jessi Slaughter but there have been many other girls. In 2009 Dahvie was even arrested on charges of statutory rape on a 15 year old fan but managed to get out of it because the girl was bullied into dropping the charges. Several other girls have also posted on Twitter and Tumblr about alleged rape or molestation by Dahvie. He's also been known to send nude pictures and explicit messages to his underage fans, and his music often has extremely sexual lyrics which are performed to audiences of mostly teens and tweens.
Unfortunately BotDF has rabid fan girls who bully into silence anyone who tries to come forward about Dahvie's antics. People who have worked with Dahvie (most notably, Jeffrey Star) have spoken out about the weird shit they've seen, but usually the actual victims themselves are shamed into submission.
