Legally Speaking- Facebook
Legally speaking, children younger than 13 shouldn’t be on Facebook or Twitter. Many children bypass this law, even on sites that enforce it, by simply adjusting their birthday.
“Facebook was never intended for kids younger than 13,” she says. “Kids click on things. Which can be a problem, not just with friending people, but also the malware they pick up online.”
What you can do
1. Social Networking Sites have Terms of Service agreements when you first join them. It would be good to read them before you sign up so you know what you are letting yourself in for.
2. Get control of your Facebook Privacy Settings- go to Account and then privacy settings
3. Learn how to report abusive or inappropriate material. Most social sites have ways of blocking or reporting bad behaviour.

How Facebook looks in real life.
Your digital footprint
It’s great to share things online with your friends. Part of the fun of sharing videos, images and other content, is that lots of people can view and respond. Remember that what you share with your friends may also be viewed by others who you don’t know. They may also be able to look at it for years to come. Everything you post adds up to make your digital footprint and, once it’s online, it could be there forever. So think before you post.
