 ancouver native Amanda Todd, 15, was found dead last week in an apparent suicide, evidently pushed over the edge by persistently cruel bullying, online and in real life. And now, the vigilante hacker group Anonymous claims to have identified — and unmasked — her virtual harasser. A guide to the developing story: 
 
 What exactly happened? 
 
 Before she allegedly committed suicide, Amanda detailed how the harassment started in a confessional YouTube video she posted in September. Without naming names, the teen said through a series of cue cards that when she was in seventh grade she flashed a man online. A year later, the man tracked her down on Facebook, demanded more salacious photos, and forwarded her original naked photo to "everyone." When Amanda moved schools, the man reportedly continued harassing her, this time creating a Facebook page using her uncensored photo as the profile picture, inspiring real-life harassment and beatings from her fellow students. 
 
 And who is this alleged tormenter? 
 
 The hacking group claims that a 30-year-old Facebook employee from New Westminister, British Columbia, harassed Amanda so relentlessly that she took her own life. In a newly released YouTube video, a man wearing a Guy Fawkes mask says in an auto-tuned voice that the man "is an abomination to our society and will be punished." Anonymous further distinguishes "Amanda Todd's punisher" in a post on Pastebin, saying: "This is the pedophile that social engineered Amanda Todd into supplying him nude pictures." They include his online user name, birthday, and location. 
 
 What does the alleged harasser say? 
 
 He doesn't appear to have spoken publicly since Anonymous unmasked him. But earlier this week, he reportedly appeared in court on unrelated charges of sexual assault and sexual interference with a minor. At the time, he claimed he was Amanda's friend and reportedly blamed a man in New York for harassing her. 
 
 Is there further proof against this man? 
 
 Yes. Vice magazine published information that allegedly connects Amanda and the man, including screenshots from Facebook posts and "jailbait" website accounts. The man allegedly posted images of nude teenagers to such a forum and reportedly "made it known he was blackmailing underage girls." 
 
 How are people reacting to this awful tale? 
 
 Obviously, this guy is "in for a world of pain," says Laura Beck at Jezebel. Thankfully, there's "steady momentum in the direction of increased intolerance of this specific brand of internet bullshit." But Anonymous has hardly solved the larger online bullying epidemic, says Patrick McGuire at Vice. "The vigilante justice of Anonymous is simply a band-aid on a very serious and quickly growing problem online that is putting vulnerable young girls like Amanda Todd in a very complicated and destructive type of danger." The disturbing trend requires further examination "under a more complicated lens." 
 
 Editor's note: This article has been revised since it was first published. ||||| Canadian authorities are investigating the circumstances surrounding the death of 15-year-old Amanda Todd, who made a heartbreaking video chronicling years of bullying in school and online, previous suicide attempts and humiliation that lasted up until her death. 
 
 Authorities have opened a probe into her death and "anyone that had contact with her" before she died, police said. 
 
 Todd posted the video called "My story: Struggling, bullying, suicide, self harm" on Sept. 7 and was found dead in her home town of Port Coquitlam, British Columbia on Oct. 10. Since her death, the video has been viewed more than 3 million times. 
 
 In the video, Todd described using webcam chats to meet and talk to new people online as a seventh grade student, including a man who pressured her to flash her chest. One year later, she did and the man took a photo of her chest. 
 
 Todd said that the man put the photo online and sent it to everyone she knew. Even after moving towns and schools multiple times, the man continued to follow her online and use her photo, she said. The photo and the bullying online and in school drove her to depression, drugs, alcohol, cutting and a suicide attempt with bleach. 
 
 "I can never get that photo back," she wrote. "It's out there forever." 
 
 Authorities would not comment specifically on whether they are searching for the man Amanda claimed was cyber-bullying her, but Royal Canadian Mounted Police Sgt. Peter Thiessen said, "We're following up on a wide variety of tips and information, without getting into detail." 
 
 When asked if criminal charges could result from the investigation, Thiessen told ABCNews.com, "That would be dependent on the quality of the evidence we might get." 
 
 Anonymous, an online hacking and activist group, posted the name and address of a British Columbia man in his 30's who they claim pressured Todd for the nude photo. Contact information for the man was not immediately available. 
 
 The RCMP did not respond to requests for comment today regarding the Anonymous post. 
 
 Authorities have not officially called the death a suicide, but Cpl. Jamie Chung of the Coquitlam Royal Canadian Mounted Police said in a statement, "At this time it has been determined that the teen's death was not suspicious in nature and that foul play was not a factor." 
 
 The nearly nine-minute, black and white video showed Todd silently telling her story through a series of white cards with black marker writing on them. She can only be seen from her nose down for most of the video, occasionally moving around so that her face is visible. 
 
 "Hello, I've decided to tell you about my never ending story," the video begins. 
 
 She described the events leading up to the photo of her chest and how she felt after the photo was posted online. 
 
 "I then got really sick and got anxiety, major depression and panic disorders," she wrote. "I then moved and got into drugs and alcohol." 
 
 She described being called names, eating lunch alone and resorting to cutting herself. She also told the story of an incident where she made a "huge mistake" and "hooked up" with a boy at her school who had a girlfriend, but who she believed really liked her. 
 
 A week later, she said she received a text message telling her to get out of school and then a group of students, led by the boy's girlfriend, surrounded her at school and said, "Look around, nobody likes you." 
 
 "A guy then yelled, 'Just punch her already,' so [the girlfriend] did," Todd wrote. "She threw me to the ground and punched me several times. Kids filmed it. I was all alone and left on the ground." 
 
 Teenager Documents Bullying and Abuse Before Her Death 
 
 Todd said she "wanted to die so bad" when her dad found her in a ditch. She drank bleach when she went home and had to be rushed to the hospital to have her stomach pumped, she said. 
 
 "After I got home, all I saw was on Facebook--'She deserved it. Did you wash the mud out of your hair? I hope she's dead,'" she wrote. 
 
 Todd moved to another school in another city, but said the torture followed her through Facebook. Students posted photos of ditches and suggested she try another bleach. 
 
 "Every day, I think, why am I still here?" she asked towards the end of the video. "I'm stuck. What's left of me now? Nothing stops. I have nobody. I need someone. My name is Amanda Todd." 
 
 Authorities were called to a residence in Port Coquitlam, British Columbia, just before 6 p.m. on Oct. 10 to investigate the sudden death of the tormented teenager. 
 
 Todd said in her video that she did not want to press charges against the girl who beat her up because she wanted to move on when she moved to another city and school. 
 
 Cheryl Quinton, spokeswoman for the Coquitlam School District, told ABCNews.com, "The family was wanting to pass along that several supports were in place for their daughter on the school, home and community levels. There was a lot of intervention and a lot of support. I know that is the message that they want to convey." 
 
 Quinton didn't get into specifics of the timeline, but emphasized that Todd's parents wanted people to know that "there was a lot of support for this student." 
 
 Todd was in the tenth grade at the Coquitlam Alternate Basic Education School when she died. School officials would not release the name of her previous school. 
 
 Quinton said the death has been "very devastating" to the small school where resources are being provided to students in regards to suicide prevention and bullying. 
 
 "We typically, as a school district, don't talk about such deaths but with the family's endorsement we did choose to do so because it is important to point out the dangers associated with social media and cyber-bullying," Quinton said.
– Canadian authorities have opened a probe into the death of Amanda Todd, a 15-year-old who posted a YouTube video describing years of bullying, then apparently committed suicide little more than a month later. Amanda described in the video being pressured to show her breasts to a man online. He took a photo, posted it online, and sent it to everyone Amanda knew; the photo even followed her as she moved towns and schools, she said in the video. Authorities won't say if they're looking for that man, but want to talk to "anyone that had contact with her" before she was found dead in her British Columbia home town a week ago, ABC News reports. Authorities are not officially calling it a suicide, but have ruled out foul play and say the death was not suspicious. Amanda described in the video how the photo led to cyberbullying and bullying at school—and then depression and anxiety, drug and alcohol use, self-harm, and even a suicide attempt. She told one specific story of being beat up by a girl after she "hooked up" with the girl's boyfriend. "She threw me to the ground and punched me several times," Todd wrote on a cue card she held up in the video. "Kids filmed it. I was all alone and left on the ground." She said she "wanted to die so bad" when her father found her, then drank bleach and was rushed to the hospital; students continued to bully her over the incident and suggest she drink bleach again. Hacking collective Anonymous yesterday revealed the man it says took Todd's photo—click for more on him.
