ABC boss David Anderson has told journalists that their use of social media should not compromise the national broadcaster’s “independence and integrity” – and if they do, they risk being shown the door. The warning comes after the ABC found itself in the spotlight following tweets from several high profile people, including 7.30’s Laura Tingle and Four Corners’ Sally Neighbour. And then there’s journo Louise Milligan – she tweeted about rape accusations against Industry Minister Christian Porter and she is being sued by Queensland MP Andrew Laming over tweets alleging misconduct. The ABC is covering her legal costs, but yesterday Anderson said staff could be personally liable for their rip-snortin’ posts. In recent months, Anderson has been accused by Coalition MPs and senators of not doing enough to rein in his people’s extracurricular online activities.
