OK:
If someone says something APATHETIC (which means nor good or bad) just ignore it!!! It can cause a lot of trouble if you try to defend yourself when its nothing to fret about!!! But also, to prevent bullying:
Do not post rude comments!
If a fight it about to start get out of the way!
If you feel like someone's causing you problems, block them!

You shouldnt take ANYTHING too serious on the internet. Most people are jealous or just rotten....but dont freak out too much.
If you want, post this as your status. It might help. It might not. I just want some people to read this.
