A cybersecurity firm found that bots were promoting GameStop stock on social media before and after the stock's frenzied rise last month, Reuters reported. Massachusetts-based PiiQ Media says social media bots promoted Dogecoin, GameStop, and other "meme" stocks in posts on Facebook, Twitter, Instagram, and YouTube. The firm estimated that tens of thousands of bots participated, but it's still unclear how much influence they had or didn't have on the rise and fall of GME and other stocks.
