Am I The Only One That Thinks It's Wrong For Little Kids To Have A Facebook Account?

[Hiedi]

I have a niece who recently turned 13, before she hit the 'I know it all' mark, she created a facebook account. Well, I was just going through her news feed and wall, and some girl her age posted something really mean on her wall. It said "Hey lil girl u ain't nothin ain't got time for you bitch"....
WHY ARE PARENTS LETTING THEIR KIDS GET ON FACEBOOK WITHOUT SUPERVISION?
My niece doesn't do anything but post a bunch of drama, oh, like her life is so hard! She is barely a teenager!
I'm half near tempted to call up her mom & her grandmother to tell them she doesn't need to be on there, I'm really close with them and if I say something I have no idea what will happen.

I just don't think little kids need to be on Facebook, Twitter, or any other social network for that matter. I mean, if you're under the age of 16, you should not have access to any social network! It's dangerous,

I know what it's like to be a 13 year old girl, I was one, but why get on facebook and post crap like 'OH I HATE MY LIFE UHH!'...?

It just bothers me, am I the only one that thinks this is crazy?
