When people stalk you on the app to bully you, what do you do?

Four girls have been stalking me on this app, and I'm so fed up with it. They're bullying me, and I don't understand why. For example, someone was saying something about a smell. Like they liked vanilla or whatever, and I said I don't care what the smell as Lon as it smells good. So these girls start attacking me saying things like "pick what we pick you stupid whore" or "dumb cunt, whatever, you're so fake". Like rude. What did I do to you? What do I do? I'm not fake, thanks for trying to start a rumor. Also, I'm a "dumb cunt" for not agreeing? Like what!? I'm sorry I don't like musky smells and like sweet smelling things. Excuse my nose for wanting pleasant smells. I'm confused. Why do you hate me!? Stop picking on someone younger than 18! Can't everyone get along?
