Why shouldn't children 13 and under be involved in a social network?

[Julz]

Too many weirdos out there that can and do take advantage and hurt people.

Exposure to things that a young person shouldn't be exposed to.. ie; sex, drugs, graphic images

pedophiles

[Subtropical Zone]

they're always preying on vulnerable adults too old to recognize the evil lying beneath the gentle exterior of pre-teen children.

[The Truthâ„¢]

Because there are pedophiles out there.

14, 15, 16, 17 year olds shouldn't be on social networking sites.

Some people really do go through Facebook profiles and Myspace profiles with a fine-tooth comb. My roommate's sorority did, and a lot of employers do. Not only are they looking at your pictures and status updates, but they can also look through your page months and months back, and they can check the comments you post on other people's pictures and walls, up to 2 years back at times. Think I'm wrong? Think different, because I've seen my boss doing this.

If a boss and leaders of a sorority can see all that information, so can a pedophile.

Exemplitory Essay: Dangers Of Social Networking For Children
In today’s technology age, computers play a huge role in our day to day lives, the Internet especially. A growing trend on the Internet these days is social networking sites, such as Facebook, MySpace, Twitter, and Bebo. These sites are great for catching up with old friends and being able to communicate with people instantly without running up your phone bill.

Pedophiles
Creepy people

But seriously...
Kids should not be involved in social networking because of the dangers that lie in those sites. Pedophiles are usually on myspace, hunting and luring innocent children. It could catch people off guard. You might also wanna include this site too. A lot of R-rated things are posted on Yahoo Answers. Profanity, strong sexual content, etc. People do it, and some get away with it.
That would be a great way to start your essay.
