Instagram has started rolling out new features on the platform to combat the harrassment and bullying, especially among teenage users.
The first feature uses AI to automatically recognize if someone is posting unfriendly or harassing comments. After the user posts such a comment under a photo, the app will automatically ask them if they really want to go ahead and post this comment or if they want to reconsider and delete it. This puts the ball in their court and lets them reflect upon their actions.
If, however, you need something a bit more effective then there's another feature called Restrict. When you use this feature on a user, only they will be able to see their comments after they post them and they will have no idea that other people aren't seeing them. This method is called shadowbanning, which prevents the person being banned from taking counter measures against the ban since they have no idea they were banned. Restrict also prevents the person from seeing when you are online or if you've read their direct messages.
The AI recommendation feature is now rolling out and the Restrict feature will be coming out soon.
