Can I post things about the girls in my school on the internet and get away with it?
Why do you want to post things about the girls at school?
I'm bored and I want to do something funny.
It is not good to post things about  people at your school. They will think you are mean and you will have no friends.
Fuck all these bitches, I'm going to do what I want.
How would you feel if someone spread things about you? It's wrong to have fun at others expense. Get a hobby or something to have fun.
