Instagram unrolled new tools aimed at combatting cyberbullying on the heels of recent reports finding it to be the worst online platform for cyberbullying.

The changes to the social media platform include filtering out comments containing abusive keywords and the ability to block out entire groups.

The problem of cyberbullying warrants serious attention—particularly given studies estimating that in the U.S. up to 34% of students between the ages of 12 and 17 have experienced cyberbullying, defined as:

Having experienced repeated threats, harassment, mistreatment, or being purposely made fun of, online or through electronic devices.

Girls experience cyberbullying more frequently than boys.  And LGBTQ youth face cyberbullying up to 3 times as often.
