'Full of unbelievable nonsense' Ian Hislop'A tour de force' Jeremy Vine'An excellent piece of investigative journalism' Julia Ebner, Telegraph'A compelling guided tour of a dystopian underworld' John Naughton, ObserverMY NAME IS MARIANNA SPRING AND SOME OF MY TROLLS SAY THEY WANT TO KILL METhreats and abuse litter my social media feeds. They infect my everyday life. Sometimes the people behind the messages try to find me in person. This seems to be the price of venturing into the world of conspiracy theories, hate and algorithms.
