Amnesty International provide some important steps how to protect you from cyber trolling: Threats of violence, discrimination, harassment, doxxing (disclosing personal or identifying documents), and the unauthorised sharing of sexually explicit and private images are just a few examples of the various ways that abuse can be committed online.
