FACEBOOK at school?

I think facebook should not be aloud at school because its not always appropriate.I think they should keep it blocked so if one of our friends from somewhere else posts something inappropriate and it shows up on our wall we dont get in trouble for it. I have friends on facebook that do post some stuff that I would get in trouble for if they saw it at school.If facebook didn't allow pictures then i would say YES! facebook at school because we should still have freedom of speech (or type). If our school would just block all facebook pictures than I would love to have facebook at school but we would have to block all pictures and actually have freedom of speech (or type).I know not all pictues on facebook are bad but there is alot that are.So I think facebook should be unblocked and we should get some freedom. If certain people get in trouble on facebook than they should be banned from it but not everyone.I think they should open up facebook at school but you have to have your teacher's permission to get on it. I also think if you get in trouble on facebook at school it should e blocked for you only until you can prove you are responsible enough for it.I think it should only be opened up to high school and 8th grade students because 7th and 6th graders are not supposed to have a facebook. They are too young to have a facebook.Facebook should be opend up to all high school and 8th grade students who are mature  and old enough to have a facebook.Facebook can be a big help in school because if you forget about your homework you can get on facebook and ask someone about it.I'm also always learning on facebook no matter who it is or what the post is there is usually something inspirational.In conclusion I think Facebook should be unblocked for all 8th grade and high school students who must know that it can be taken away at any time.
