Your only as safe as you make yourself out to be
You are mostly safe on the internet if you follow these rules:
1. Have privacy settings on so only your friends can see stuff you post.
2.Don't friend any one you don't know .
3.Be nice don't be a cyber bully.
4.Don't meet any one you don't know offline.
5.Post appropriate stuff or your employer and coach could see that or your parents.
and finally 6.Keep your password secret.
If you do these you'll be a lot safer but always be cautious you never know who is who online.
