In a previous interview, Bobby Brown said that she wants to make social media a "happy place".
She said: "Social media is one of the best places in the world and one of the worst -- it counteracts itself. It sends such amazing messages; it raises awareness of situations that need to be heard. Nobody should say it isn't a platform for positivity and change. But then there are some really heartbreaking things to happen on social media and I have dealt with a lot of bullying online. I want to make it a happy place."
