Twitter banned a ton of fake accounts this quarter, and as a result, not only lost 1 million active users, but also saw their stock take a dump. Even though they made $20 million in the process. But Wall Street says that Twitter isn't growing, and as a result, the value declined. Even Facebook took a hit this week, in the single largest stock loss in Wall Street trading history. $120 Billion in lost value. Mark Zuckerberg lost over half his personal wealth. But Leo says he'll likely bounce back over time.
