If FB reassures the new IG-K is safe for kids, then many parents are probably going to trust that this is true. Now their kids will be subject to all the puke that is on Instagram, pedos will target it for grooming since the audience is specifically children. Kids will be subject to all the monetization efforts FB can throw at them. I imagine kids would also stress about competing with their friend's popularity and all of the other ugly shit grown ups subject themselves to when they obsess over IG.
