The American Psychological Association defines bullying as aggressive behavior by an individual that causes discomfort to another. Cyberbullying ranges from direct threatening and unpleasant emails to anonymous activities such as trolling. 32 percent of online teens admit to having experienced a range of menacing online advances from others. While direct unpleasant emails or messages are the most straightforward form of cyberbullying, they are probably the least prevalent in that only 13 percent of surveyed youngsters admitted to receiving threatening or aggressive messages. Even forwarding a private note to a group without permission from the sender is often perceived as cyberbullying; Pew research found that 15 percent of teens were disturbed and uncomfortable about having had their private message forwarded or posted in a public forum. Pew also found that nearly 39 percent of teens on social network have been cyberbullied in some way, compared with 22 percent of online teens who do not use social networks. Trolling, the act of deliberately inflicting hatred, bigotry, racism, misogyny, or just simple bickering between people, often anonymously, is also pervasive in social network. If you thought Trolls lived under bridge, 28 percent of America lives there, it seems.
