BBR Saatchi&Saatchi & Startupseeds have jointly created this Chrome extension which erases the bad words before they hit the message boards. The idea is that cyber-bullying has to stop, and by installing the chrome extension the bully can't bully, unless they use firefox. The extension detects offensive words like "ugly" and "kill yourself" and replaces them with positive ones instead. While I do like the geeky execution/idea I wonder if it'll have any impact at all on cyber-bullying.
