Meta Platforms  is building more safeguards to protect teen users from unwanted direct messages on Instagram and Facebook, the social media platform said yesterday.

The move comes weeks after the WhatsApp owner said it would hide more content from teens after regulators pushed the world’s most popular social media network to protect children from harmful content on its apps, a Reuters report stated.

The regulatory scrutiny increased following testimony in the US Senate by a former Meta employee who alleged the company was aware of harassment and other harm facing teens on its platforms but failed to act against them.

Meta said teens will no longer get direct messages from anyone they do not follow or are not connected to on Instagram by default. They will also require parental approval to change certain settings on the app.

On Messenger, accounts of users under 16 and below 18 in some countries will only receive messages from Facebook friends or people they are connected through phone contacts.

Adults over the age of 19 cannot message teens who don’t follow them, Meta added.
