No charges are to be brought after a woman from Sussex complained to police about two years of online abuse.
Nicola Brookes from Brighton was falsely accused on Facebook of being a paedophile and drug dealer.
She said she felt like she was being attacked "by a pack of animals".
The Crown Prosecution Service (CPS) told Ms Brookes: "You engaged with the 'trolls' contrary to the specific advice given to you by Sussex Police on at least three occasions."
