Pop stars Fifth Harmony are aiming to rid the Internet of cyberbullies by backing a new campaign to make the web a more friendly place.

The girl group has been unveiled as ambassadors for The Cybersmile Foundation, an organization dedicated to eradicating online abuse, and they hope to use their fame to spread positivity on social media.

Scott Freeman, CEO of The Cybersmile Foundation, says of the new drive, "Cybersmile are immensely proud to welcome Fifth Harmony on board as official Cybersmile ambassadors. It's wonderful that the girls will be using their position as role models to encourage Internet users to spread positivity to others. Their support will enable us to promote positive digital citizenship to more people and look forward to working with them to tackle cyberbullying."
