Where does the responsibility start and end?

When sharing online learning with young people, like Room5ians, how far should the school go to make sure no one sees anything "dodgy", like advertisements aimed at adults...?
Do we stop young people from watching tv, reading, newspapers, walking down the main street? All of these places have mild adult content everywhere.
Does learning in the real world environment allow teachers to help students understand safe ways to cope with things they will be bombarded with anyway, outside of school?
It's like the cyberbullying issue. We ban phones to avoid txt bullying and worry about kids bullying online, but most if not all bullying happens face to face or in whispers around the playground. Do we ban access to the playground?
What do you think? Kids? Anyone?
Just wondering... :-)

Well done Mr Jones and Rocking former Room5ians!

Does anyone know what I'm talking about? Please ask him to clarify and send him my congratulations :-)
Also big ups to former Room5ians who were going for it at the Band competition on Friday :-)
I see the defection of Mrs MacKenzie has meant that Fairfield has won this time, just like you won last time with her help. She must be great! You must be great!
