(Reuters) – Instagram announced Tuesday that it would be more strict about what content teens are allowed to share on the app. It will also encourage them towards other areas if they linger on one subject for too long.

The social media site announced in a blog post that it was making a number of improvements for teens. Adam Mosseri from Instagram will be testifying in a Congressional hearing about the protection of children online.

Instagram (NASDAQ:) and Meta Platforms Inc its parent, have come under fire for their use of services that could pose a threat to the mental and physical health and safety of young users.

Mosseri stated that Instagram had removed the option for teens to be tagged or mentioned on their account. In January teens would be able delete bulk of all their past comments and likes.

He stated that Instagram is looking at ways to restrict potentially dangerous or sensitive content for teens via its search function and hashtags.

According to the blog, Instagram launched its Take a Break feature in Australia on Tuesday. It reminds users that they should take a moment and pause the app when using it for longer periods of time.

Instagram said that in March, it will launch the first tools for guardians and parents to track how long their children spend on Instagram.

Instagram spokesperson said that the company would not resume plans to launch an Instagram Kids version. In September, Instagram pulled out of plans to develop the app for children. This was in response to growing opposition.

This move was in response to a Wall Street Journal article that stated former Facebook employee Frances Haugen had leaked internal documents showing the company knew Instagram could cause mental problems for teenage girls. These documents included information about their body images and views. Facebook claimed that the documents leaked by Frances Haugen were used to portray a false image of their work.

Concerns about the app’s children-focused nature were also voiced by legislators and state attorneys general.

The bipartisan alliance of U.S. attorneys general stated last month it was opening a probe into Facebook to see if the company promoted Instagram to kids despite possible harms.
