There's a lot of talk about cyberbullying these days, but not necessarily a lot of action. That's why Adweek issued a creative challenge to agencies, which were asked to come up with campaign ideas to reduce abusive behavior online. Like our previous challenge on anti-Muslim tensions, digital bullying is one of the hottest topics of the day. It can make life worse for people of all ages. One especially horrific example was the recent suicide of Rutgers University student Tyler Clementi after an illegally recorded video of his sexual encounter was posted online. Such deaths have already sparked the popular video campaign "It Gets Better," with such high-profile contributors as President Obama. For Adweek's challenge, six agencies offered up their own big-picture ideas. We'd be much obliged if you'd check it out.
