Instagram To Limit Interactions, Between Teens and Adults. The new polices are aimed at making the app more safe for teens and children. Adults are now banned from sending direct messages to teens, unless that user follows the adult. Teens who send direct messages to adults will also receive “safety prompts” if the adult has exhibited “potentially suspicious behavior.”. These notices will encourage users to “be careful sharing photos, videos, or information with someone you don’t know.” . Teen users who are new to the site will now be encouraged to make their profile private. Instagram is also instituting new AI technology to attempt to detect the actual age of users when they create a profile. These policies will go into effect this month in some countries. They will be implemented globally “soon.”
