So there is this social app for kids called PopJam and it has almost a million children, it is very popular. Since there are so many kids on it, I suggest maybe you should make a business account (business and celebrities such as McDonalds, Nintendo, Jojo Siwa, GEMSisters, Crayola, Disney, Nickelodeon etc use PopJam) to advertise and tell people to get KS and stuff.
