Well that could be due to the huge virus that is on it : The virus tells you that you have been tagged in a photo, so thinking that there is a new photo of you, you click on the notification. But once you do, the virus goes through everything on your computer and has access to your account (facebook, emails, and if you've logged online to your bank account) and once its gone through everything, it will destroy your hard drive and you have no computer.
It's one facebooks official facebook page and ABC's facebook page.
