Online harassment and attacks on journalists – including threats, insults, and smear campaigns – are increasingly deployed as a means to silence journalists and challenge their credibility in the public arena. While addressing online harassment and its negative impact on the free flow of information requires a multi-actor approach, newsrooms have a key role to play in protecting their journalists from the professional and personal harm that harassment can produce. This Protocol outlines a four-step framework that newsrooms can take to more effectively protect targeted journalists from the professional and emotional impact of online abuse. The protocol is not intended to be a one-size-fits-all. Instead, it offers a framework for newsrooms to tackle the issue of online abuse and provides a series of specific measures that newsrooms can adopt and adapt according to their particular situation.
