Fake news has become a major issue worldwide. It’s capable of driving nations’ political paths and influencing elections. And to help fight this phenomenon, Brazilian agency Artplan and Metro Newspaper turned to technology. We all know captcha, that tool designed to check if you are a robot. But, at Metro’s website, it was redesigned. Instead of selecting random images, the user must select which image has a piece of fake news. After the answer, a brief explanation with the true fact appears and the user can move on to comment. Every day, a different piece of fake news was shown, keeping readers up-to-date. "Press vehicles have not only the responsibility of combating fake news, but of intelligently using their biggest asset, which is credibility", says Cláudio Bianchini, Brazil’s Metro president. Zico Farina, Artplan’s creative director adds that “using technology is the best way to fight fake news. And being able to redesign a tool like captcha is a way to use the system at our favor.” In order to use the tool, just access metrojornal.com.br e comment on any news.
