One of its new programs is geared toward ferreting out bullying comments.
"They're using artificial intelligence," said ABC News' technology and consumer correspondent Becky Worley. "These are algorithms trying to guess if a comment is abusive."
Instagram also has keyword filters that block out specific words associated with abuse and a new group-blocking feature that allows users to block entire groups of people, not just individuals.
“Kindness has been in the DNA of Instagram from our earliest days, and as our community grows -- now to 800 million -- we are working to make Instagram the kindest and most inclusive online community," Instagram COO Marne Levine said in a statement. "We want Instagram to be a welcoming platform for people of all backgrounds to express themselves. One way we're doing that is by providing tools that enable people to control their own comment space."
Worley said the social networking app, which is owned by Facebook, is clearly making the changes for more reasons than improving the safety of its users.
"They say this is about kindness," Worley said. "If they want to differentiate themselves, they have got to keep the flame wars to a minimum."
Seventy-six percent of American teens ages 13 to 17 use Instagram and 25 percent said they have experienced repeated cyberbullying on their cell phones or the internet, according to the U.S. Department of health and Human Services,
How to enable comment controls
