A new study confirms what many Internet users know all too well: Harassment is a common part of online life.
The report by the Pew Research Center found that nearly three-quarters of American adults who use the Internet have witnessed online harassment. Forty percent have experienced it themselves.
The types of harassment Pew asked about range from name-calling to physical threats, sexual harassment and stalking. Half of those who were harassed said they didn't know the person who had most recently attacked them.
Young adults — people 18 to 29 — were the most likely age group to see and undergo online harassment.
The survey was conducted between May 30 and June 30 among 3,217 respondents.
