The Internet can be a powerful tool, allowing people to communicate and conduct business across borders. Unfortunately, that also makes it easy for people to, often anonymously, threaten others — or worse — post content that they don’t like. This series tells stories of folks whose lives were ruined because they did something as simple as sending a tweet or posting a status update. Each episode features two people whose lives were turned upside down because of a few keystrokes. The true tales include a woman who received death threats for sending a tweet calling for a cable show’s cancellation, a British man who was detained by the Department of Homeland Security because British slang was misunderstood, and a woman who was forced to move out of her town because of violent threats directed toward her for using the wrong emoji on Facebook.
