Think ugly selfies or complaints about an awkward encounter that you wouldn't want your entire Instagram audience to see, Brooke Erin Duffy, an assistant professor of communications at Cornell University, said in a post for Quartz.

"Such acts of digital self-surveillance make sense against the backdrop of widespread media coverage of social media gaffes," Duffy wrote. "We often hear about employees losing their jobs after publishing a distasteful image or a tactless tweet."

Last year, 19-year-old Harley Barber, a now-former student at the University of Alabama, was kicked out of her Alpha Phi sorority and removed from the university after racially charged videos she posted to her Finsta surfaced online.

According to a survey of more than 10,000 people aged 12 to 20 conducted by anti-bullying charity Ditch the Label, 42 percent of Instagram users had been bullied on the platform.
Instagram was also deemed the worst social media network for mental health by scientists in the United Kingdom, who surveyed nearly 1,500 young people aged 14 to 24.
