Step 1: Do not post personal info on the internet or best friends.
Because they could use it to hurt you.
Step 2: Do not share passwords with anyone.
They could use it and buy apps or use them to get you in trouble.
Step 3: If people send you mean things don't respond save them and tell an adult.
Because the adult can help you and then you don't have to worry about it.
Step 4: Do not talk online to people you don't know.
Because they could ask you personal things in a sentence and you may not even know.
Step 5: You should have your settings set so friends can only see it.
So that people do not use that and make the same profile and you don't know about it.
