You obviously have had no clue what cyber bullying is then.
Nobody is directly attacking this girl. She can go about her daily life without any sort of complications if she chooses to. That includes being able to check her twitter and facebook. No one even knows her name.
Facebook (a public corp with lawyers who specialize in this) agreed that it's not cyber bullying, so I'll take that educated fact over what you're copy/pasting from whatever website you just googled to support a flawed opinion.
