Excerpt from this article:
Because bullying on your main feed is seen by many as aggressive and uncool, many teens create hate pages: separate Instagram accounts, purpose-built and solely dedicated to trashing one person, created by teens alone or in a group. They’ll post bad photos of their target, expose her secrets, post screenshots of texts from people saying mean things about her, and any other terrible stuff they can find.
Sometimes teens, many of whom run several Instagram accounts, will take an old page with a high amount of followers and transform it into a hate page to turn it against someone they don’t like. “One girl took a former meme page that was over 15,000 followers, took screencaps from my Story, and Photoshopped my nose bigger and posted it, tagging me being like, ‘Hey guys, this is my new account,’” Annie said. “I had to send a formal cease and desist. I went to one of those lawyer websites and just filled it out. Then she did the same thing to my friend.”
