A woman who goes by the name of Poison Ivy is encouraging vulnerable men to sexually degrade themselves online, before pushing them to commit suicide, it has been claimed.
A man has even confessed he "poured vinegar down his penis for her".
On her Twitter profile, Hanna, 17, says she seeks out "weak" men and rips apart their self-esteem to make herself "grow stronger".
She shares pictures of her followers, which are close-up selfies, with some shots of them in underwear, with her name written on their foreheads.
Her bio says: "I treat all men like shit because they are weak and they deserve it.
"I bully the weak to make them weaker as I simultaneously grow stronger."
What a b****!
A chilling video has surfaced revealing how brutal her sinister activities really are.
The clip made by MarsRPG calls for victims to report her and put an end to the abuse.
The five minute film has been viewed over a quarter of a million times.
The voiceover says: "She encourages guys to do disgusting acts, via webcam on a live screen, like showing their genitals, spreading their butt cheeks on camera and sticking objects up their a**.
"While doing this they shout 'I love you Hanna!
"She finds weak, socially awkward guys who have never had a girlfriend or a social life."
Hanna has numerous tweets on her feed that glamorise suicide, which many men pick up on.
One man revealed his experience with Poison Ivy to MailOnline, he said: "I would consider suicide if she would take herself with me.
"I don't get much attention. I've always been a loner. I dig dirt for a living, making holes in the ground to make swimming pools. So I don't get out much.
"I see myself a inferior to her so the rules don't necessarily apply to her.
"I know it sounds crazy but if you're in the situation and get the kind of attention you've never experience before you overlook the hypocrisy.
"We basically share her. I'm OK with it. But a few others take it too far.
"She tells me what she wants me to do over Skype. I love to Skype.
"So yeah I do some pretty weird stuff for her but it's worth it cause she gives me attention.
"I'd never question her motives for fear that she'd stop talking to me."
Hanna even convinced one man to shave off his hair, beard and eyebrows, telling the man "it will look hot" but once he does and insecurely asks her if she likes it, she replies "Do you want me to be honest? No."
She adds: "I just wanted to see what you look like with no eyebrows."
As well as this, she convinced him to put his head down the toilet in another video.
It is not known if anyone has committed suicide for her, but her tweets imply that this is her aim.
She wrote: “Romance is very stupid and everyone always breaks up in the end, or it ends some way or other.
“And the only way to do is properly is for a couple to suicide together, because that way they will have been together forever, as they surely promised each other.”
Thankfully, the Twitter profile has been suspended.
