I'm glad that more emphasis is being put on bullies these days. Growing up it "wasn't a problem" or "every kid does it" in my era, so I'm glad it's getting recognition that it can really ruin a child's life. (this is all coming from the Keaton Jones video).
What can be done? I'd love to say, if it's done at school, teachers should have stricter punishments for them - but bullies are smart enough to not do it in front of adults.
