An anonymous reader writes: A campaign taking shape in Brazil seeks to fight online harassment in an unusual way: by posting the abusive comments on real billboards. "The group collects comments from Facebook or Twitter and uses geolocation tools to find out where the people who have posted them live. They then buy billboard space nearby and post the comments in huge letters, although names and photos are pixelated." Brazil has laws prohibiting racial abuse, but this group doesn't think the government is doing enough to stop it. The campaign's founder said, "Those people [who post abuse online] think they can sit in the comfort of their homes and do whatever they want on the internet. We don't let that happen. They can't hide from us, we will find them."
