Internet trolls have been around ever since the first website went live and even then, trolls weren't as mean as they are today. Hiding behind a username to say horrible things to another person that you don't know is a very dark part of the internet that started on forum boards and comment sections on blogs like these. It has now transcended to social media sites and unfortunately the troll game has gotten a lot bigger and smarter. Most people will create new accounts if they have been banned from a forum or a social media site and the cycle of harassment will continue with little to no admin or moderator intervention.
