While the coronavirus pandemic has slowed down or entirely shuttered much of our world, neither organizing nor the hatred and violence that makes that work essential have stopped. Much of our collaboration and gathering has moved onto the internet; there, we have begun to encounter "Zoombombing" and other kinds of disruption and harassment familiar to gamers and others who have long used the internet for much of their social interaction and engagement. By combining the community safety principles, practices and skills we already use in our movement work with some easily accessible technical know-how, our organizations and communities can become better equipped to prevent and defend against the violent disruption of our work as it moves online.
