The Green Bay Packers and the Chicago Bears are two American football teams. Both teams have a lot of fans, and the fans have their own websites and internet forums. On these pages, they share photos, stories and jokes about the games and the players. But one day in 2013, a "joke" became an example of cyberbullying.

A fan uploaded a photo of a Green Bay Packers cheerleader to the Chicago Bears' Facebook page. He added an unkind comment about her appearance and invited other Chicago Bears fans to the same. They called her ugly and said that the Green Bay Packers had the worst cheerleaders in America. To them, it was just a joke. But how did that cheerleader feel?

The name of the Green Bay Packers cheerleader in the photo was Kaitlyn Collins. She found her photo on the Chicago Bears' Facebook page, read the comments and was very upset. She complained to Facebook, but they did not remove the photo. So Kaitlyn decided to fight against the bullies in her own way. She made a video and posted it on YouTube.

In her video, she did not speak; she wrote messages on paper and showed them to the camera. She explained that most of the comments were "too horrible to repeat" but they had the same theme: they said she was "ugly." She also explained that some comments were different - they were kind. One comment said: "I'm a Bears fan, but she is not ugly" - and she is somebody's daughter. Her video became a viral story.

After that, somebody from the Chicago Bears fan club deleted the photo from its Facebook page. It gives a message about the dangers of cyberbullying. And now Kaitlyn has her own channel on YouTube. Her videos continue the fight against cyberbullying.
