Nearly 120,000 electronic signatures have been recorded in an online petition to ban an app with the potential to be used for cyberbullying.

The petition, started by Queensland mother Katrina who does not want to disclose her last name, follows in the wake of the suicide of Northern Territory teen Amy “Dolly” Everett earlier this year.

The petition aims to ban social networking app Sarahah, which allows users to give anonymous ‘feedback’ to users.
