Imagine you wake up one morning to find your name, photo, contact details and workplace published on social media, where you are wrongly accused of all manner of sins in an antisemitic online campaign that spreads on the internet in what seems like milliseconds.

Death threats follow. You are afraid to leave the house. You lose your job, friends or customers. Or you are shunned by colleagues. Or all of these things happen based on the false information disseminated online.
