Facebook is the largest Social Media on the web, and its problems are far from over.

After being criticized for spreading fake news and algorithms update that affect news publishers, it's under fire when child advocacy group Campaign for a Commercial-Free Childhood (CCFC) wrote an open letter to Facebook’s Mark Zuckerberg in which they outlined their objections to Facebook’s child-centered app, Messenger Kids.

The letter has been signed by more than 100 organizations and individuals, was wrapped with CCFC asking Facebook to delete the app.

On social media networks, there is an age limit to which permits only those of the age older than 13 can sign up. But the thing is, parents are still allowing their kids to sign up, or even help their kids to fake their birthday date so they can have a social media presence, like everyone else.

So here, Facebook's solution, was to create a platform dedicated for those 13 and below users.

In short, Facebook's Messenger Kids, is a Facebook's Messenger, for kids.

A Messenger spokesperson said in a statement:

But here, the CCFC also acknowledges that there is a niche for online messengers:

Parents should know that digital media is virtually unregulated. Research have concluded that spending three or more hours a day on electronic devices risk higher rates of depression, loneliness, sleep deprivation, and risk factors for suicide.

Experimental studies have also shown that time on digital media leads to unhappiness, rather than unhappiness leading to more digital media use. And since smartphones became common, rates of depression, intentional self-harm, and suicide among teens have skyrocketed.

Previously, even Facebook's co-founder Sean Parker and Chamath Palihapitiya have spoken their thoughts. They really suggest that social media should be regulated, and Facebook is ripping the society apart.

While Messenger Kids is said to not track users to target them with ads. But with kids having their own social media presence, the best thing for parents to do, is to at least limit the time their kids spend on the app, and make sure that their online activities are supervised.
