13. STUDY ON FACEBOOK AND TWITTER
 A study found that people think privacy is important for the protection
of reputation and against social surveillance. (Kwok Choon, 2018)
 It found that users on Facebook expect to have control over personal
info, but are aware of privacy risks – some violations can harm
careers.
 On the other hand, on Twitter, the study found publicity is more
important than privacy.
 People in the study thought their Facebook profiles were at the
privacy they expected, but they later found out how much information
is readily available to strangers. Only then did they look and change
their privacy settings.
 Study ultimately found that people don’t think about social media
privacy until their privacy is violated. (Kwok Choon, 2018)
