Bear Blogging

I think I might be in trouble. The bears have found a teddy social networking site, The Bear Club that offers the chance to chat with other bears. I caught the polar bears working on trying to get onto it a bit ago to make a post titled "Single Polar Bears with cubs looking for same"! And there's at least one boy polar bear on there that I've seen so far, too! Does anyone know how block such a dangerous site?
