To try to prevent bullying instagram will ask people to confirm if they want to post a message if it matches comments that have been reported. The example they use is "You are stupid and ugly".
Interesting to see how heavy handed it will be as many accounts are a total echo chamber where simple questions are deleted and probably reported.
Instagram said it will also soon begin testing a new feature called "Restrict" that will allow users to hide comments from specific users without notifying those users that they’ve been muted.
