It is widely believed that young people are hopelessly devoted to social media. Teenagers, according to this stereotype, tweet, gram, Snap and scroll. But for every young person hunched over a screen, there are others for whom social media no longer holds such an allure. These teens are turning their backs on the technology – and there are more of them than you might think.
"Cyborgs", a combination of a human and a bot, are used to spread fake news or create a marketing "buzz". Cyborgs can be bot-assisted humans or human-assisted bots. An example is a human who registers an account for which he sets automated programs to post, for instance, tweets, during his absence. From time to time, the human participates to tweet and interact with friends. Cyborgs make it easier to spread fake news, as it blends automated activity with human input. When the automated accounts are publicly identified, the human part of the cyborg is able to take over and could protest that the account has been used manually all along. Such accounts try to pose as real people; in particular, the number of their friends or followers should be resembling that of a real person. Often, such accounts use "friend farms" to collect a large number of friends in a short period of time.
Another survey conducted (in 2015) by Pew Internet Research shows that the Internet users among American adults who uses at least one social networking site has increased from 10% to 76% since 2005.

According to Nielsen, Internet users continue to spend more time on social media sites than on any other type of site. At the same time, the total time spent on social media sites in the U.S. across PCs as well as on mobile devices increased by 99 percent to 121 billion minutes in July 2012, compared to 66 billion minutes in July 2011. For content contributors, the benefits of participating in social media have gone beyond simply social sharing to building a reputation and bringing in career opportunities and monetary income.
