Fizz is a mobile app that lets college students post anonymously to their campus community, verified only by a school email. Fizz sells itself to students as a fun, casual campus-exclusive feed to share jokes, memes, and gossip. However, Fizz quickly becomes a place for targeted bullying, false accusations directed at students and staff, and pile-ons that spread rapidly. Unverified information about campus events can be misleading and even dangerous.
