Former Carnegie Mellon student here. A couple students had a private argument over chat (facebook messenger) in which one student said some things that were not politically correct. The other student screenshot-ed the messages and posted them in the largest facebook group, with over 10k members. The post was heavily upvoted, and the student who made the non-politically correct comments received death threats and hundreds of angry messages. The student wrote a long apology to the community for their behavior and a planned "re-education" program they were undertaking to be better educated.
